BACKGROUND OF THE INVENTION 1. FIELD OF THE INVENTION This invention relates to glass compositions and more particularly to fiber glass compositions, and mathematical relationships of the ingredients of the glass compositions to identify thermal properties of the glass compositions forming and l[quldus temperatures with an acceptable temperature difference to prevent devitrification of the molten glass during forming of glass fibers.

Discussion of the Technoloav In the art of forming glass fibers it is recognized that the difference between o the forming temperature and Ilquidus temperature is maintained at a value to prevent devftrifloation of the molten glass during fiber forming. For example, the most Scommon glass composition for maldng continuous glass fiber strands for textilee and Sglass fiber reinforcements is known in the trade as "E glass". The requirements as Sto what type of composition constitutes an E-glass composition are Included In ASTM o D578-00. An advantage of using E-glass having 6-10 percent by weight B0 3 is that its liquldus temperature is well below its forming temperature, i.e. typically greater Sthan 56C (100 0 F) and usually in the range of 83 to 111"C (150 to2D00F). As used c herein, the terms "forming temperature', "T, 1 "log 3 forming temperature" and "log3 F" mean the temperature of the glass at which the viscosity of the glass Is log 3, or 1000 poise, and the terms liquidus temperature', liquidus T and

T

ua" mean the temperature at which the solid phase (crystals) and liquid phase (melt) of the glass are in equilibrium. The difference between TFORM and Tu, referred to herein as "defta T or is a common measure of the crystallization potential of a given melt composition. The lower the AT, In other words the smaller the difference between the forming temperature and the liquidus temperature, the greater the crystallization potential. In the glass fiber forming Industry, AT is typically maintained at a temperature of at least 50C (90oF) in order to prevent devitrification of the molten glass during a glass fiber forming operation, In particular, in the bushing area.

It Is appreciated by those skilled in the art of forming glass fibers, that it is desirable to operate the glass fiber forming operation at low temperatures because operating the glass fiber forming operation at high temperatures results in highenergy usage, along with associated high-energy costs. In addition, the high temperatures accelerate degradation of the refractories used in the glass melting furnace, as well as the bushings used to form the fibers. The bushings include preclous metals that cannot be recovered from the glass as the bushings wear.

It Is recognized that boron and fluorine in addition to contributing to the electrical properties of the E-glass, e.g. dissipation factor and dielectric constant, also lower the forming and llquidus temperatures of the glass while providing a AT of at least 50C (90F). The boron in the form of an oxide and fluorine In the form of a fluoride are included in the glass batch materials and act as fluxes during the glass COMS ID No: SBMI-05827336 Received by IP Australia: Time 17:25 Date 2007-01-05 05/01 2007 16:34 FAX COLLISON CO IP AUST CANBERRA I012/088 4 r-- Smelting operation. E-glass can include up to 10 wt% B 2 0 a and up to 1.0 wt% fluoride (see ASTM D 578-00 Although the boron effectively lowers the forming and Iquidus temperatures while providing an acceptable AT value and the fluoride or o fluorine acts as a flux, there are drawbacks. More particularly, these materials volatilize during melting and move with the exhaust gases into the exhaust system. If the boron and fluorine In the exhaust gases are not removed they are released to the o atmosphere. Since boron and fluorine are considered pollutants, these emissions are closely controlled by environmental regulations, which in turn require careful o control of the furnace operations and/or the use of costly additional pollution control to equipment. In response to these concerns, the boron andlor fluorine content In E- Sglasses were reduced. For example, U.S. Patent Nos. 4,542,106 and 5,789,329 and Cl WO 98112858 disclose boron free or low boron e.g. 1.Bwt% glasses having a forming temperature In the range of about 1258 to 1263°C. As can be appreciated by those skilled in the art of glass making, reducing or removing the boron and/or fluorine content in the batch materials raises the forming temperature. More particularly, the silica content increases as the boron content decreases, resulting in an increase in the forming temperature. As mentiloned above, Increasing the forming temperature results in high-energy usage, high-energy costs, and acceleration of the degradation of furnace refractories and bushings used to form the fibers.

In general, glass compositions having particular properties, e.g. forming temperature and delta T are Identified by weight percent andfor molar percent of the components or ingredients in the glass. As can be appreciated by those skilled in the art of glass making and/or glass fiber forming, it would be advantageous to identify the performance of the glass compositions not only by the amount of a particular ingredient in the glass but also by a relationship, e.g. a mathematical relationship of the Ingredients in the glass. WO 01/32576A1 discloses fiber glass compositions and the mathematical relationship of several of the ingredients, e.g. the combined Wt% of CaO and MgO, and the ratio of AlaO/CaO, in the glass. Using the combination of glass Ingredients, e.g. the absolute weight percent of silica with the relationship of COMS ID No: SBMI-05827336 Received by IP Australia: Time 17:25 Date 2007-01-05 05/01 2007 16:34 FAX COLLISON CO IP AUST CANBERRA I013/088 0 other ingredents In the glass, e.g. the ratio of silica to RO (combined Wt% of CaO and MgO) would provide information regarding the melt properties of the glass.

Further in the preceding discussion, in the following discussion and in the caims, the terms "weight percent".

and 'percent by weight" are used herein interchangeably.

In one embodiment of the present invention, the mathematical relationships of the Ingredients of a generic quatemary glass system are disclosed. The quaternary system Includes SiO 2 CaO, A6iOa and MgO. As can be appreciated by those skilled in the art of making glass, in particular making glass fibers, MgO if not added to the COMS ID No: SBMI-05827336 Received by IP Australia: Time 17:25 Date 2007-01-05 05/01 2007 16:35 FAX COLLISON CO IP AUST CANBERRA IA016/088 8 0 0 batch materials is found In the batch materials as a tramp material, e.g. MgO is found c3 in clay at 0.3 to 0.5 percent by weight. In the practice of the Invention, MgO is added to the batch material to attain a level In the glass greater than the tramp level. The o relationship of 810,, CaO, AIO and MgO of interest include RO CaO MgO, SiO/CaO, SiOlRO, SIO/A!0s; AI2/OCaO; 8O1 AlMOs; SO12 RO and AItOa/RO or RO/AI2Oa. In the present Invention when other ingredients or components are Sadded to the glass batch materials to alter the forming and/or tiquidus temperatures Sof the glass andfor ae present In the glass, for example but not limiting to the o invention NaO, L K&O and BO the following mathematical relationships are of interest, (SiO AlaOa)(R20 RO 8,0s) where RO Is as previously defined and NaO UO2 120. In Tables 1 through 22, the relationship (SiOa C AlaOa)/(R20 RO BOa) is shown as (Si AI)(R20 RO B) to fit the formula into a reasonable column width. Each of the compositional features of the glass identified above reflects the relative balance between the fluidity viscosity) of the glass melt and its crystallization potential, as will be discussed below in more detail.

The physical melt properties of Interest In the present discussion are the forming temperature and the liquidus temperature because embodiments of the present Invention are to provide low boron or boron free glass compositions having a low forming temperature and a desired AT. In this manner, the glass can be processed, e.g. to form glass fibers at a low temperature while reducing the posslbilfty of devitrification of the molten glass, e.g. in the bushing area. Without limiting the present invention, one embodiment of the Invention includes a glass composition having a farming temperature of no greater than 12400C (2264"F) and a AT of at least 50 0 C In the following discussion, the mathematical relationship is to the ingredients in the glass; however, the invention Is not limited thereto and contemplates Identifying and using the relationship of the ingredients to be added to the batch, e.g. mixing the batch prior to melting the batch to form the glass. Further, in the following discussion the mathematical relationship of the ingredients will be in wt% of the ingredients in the glass composition; however, the invention Is not IImited thereto and maybe the mole% or any measurement that identifies the amount of the Ingredient in the batch materials and/or the glass composition.

In regards to the ingredients or constituents of the quaternary system presented above, It is known that pure silica is the highest melting glass former, A COMS ID No: SBMI-05827336 Received by IP Australia: Time 17:25 Date 2007-01-05 05/01 2007 16:35 FAX COLLISON CO IP AUST CANBERRA l017/088 S9 0 0 pure silica melt does not have a well defined melting point At 2500C (4532 0 it C has a viscosity of greater than about log 4 (10,000) poise, and as I cools to room temperature, it gradually solidifies end forms a glass. Pure calcia, magnesia and o alumina melts are known to have very low viscosaltes, e.g. in the range of 0.5-2.0 poise at their respective melting points. These materials do not solidify into a glass Sas the melt cools but rather crystallize instantly at their sharply defined melting point, SIn a typical quatemary SIO,-Al~ 2 0raO-MgO glass composition with 55-60% SiC) 0 and 21-25% CaO, each oxide of the quatemary system contributes its unique Scharacteristics toward Its balance of melt properties.

0 o Based on the material properties of the constituents of the quaternry system c for a glass composition having these components, it can be Inferred that as which is the largest oxide component of the glass composition in terms of weight percent, s reduced In a given composition of this type, the melt viscosity and the resulting log 3 forming temperature drops. If CaO, which is the second largest component of the glass composition in terms of weight percent, or MgO is increased in such a composition, the effect of RO (CaO MgO) on the glass properties will be twofold. More specifically, it will not only increase the fluidity of the resulting melt (i.e.

decrease its viscosity and the forming temperature) but it will also increase the cryatal llability of the resulting melt increase its Ilquidus temperature), and therefore reduce the AT, As a result, although not required, in one nonlimiting embodiment of the present invention, the glass compositions have the lowest SiO) content that will yield the lowest log 3 forming temperature, which in the present invention Is below 1240°C, preferably below 1220°C in combination with the ratio of S10 to RO that yields the process-required AT, which In the present invention is at least 50C. Based on the forgoing and although not required in the practice of the invention, in one nonlmltling embodiment of the present invention, the silica level Is preferably no greater than 62 wt% SiOe, in order to promote a lower log 3 forming temperature. In other nonlimiting embodiments of the present Invention, the glass compositions have no greater than 60 wt% SiO and no greater than 58 wt% SiO 2 In general, MgO is included in a glass fiber forming composition because it has been found that the heating and melting profile of a glass fiber composition, and in particular the Iqluidus temperature, can be controlled and in particular optimized by COMS ID No: SBMI-05827336 Received by IP Australia: Time 17:25 Date 2007-01-05 05/01 2007 16.36 FAX COLLISON CO IP AUST CANBERRA 1018/088 0 controlling the amount of MgO. More particularly, by regulating the amount of MgO, Sthe Iquldus temperature can be selected to provide a delta T of at least 50°C. In addition, it has been determined that a eutectic exists in a generic quaternary 8 10 o AI-CaO-MgO system at around 2.5 2,8 wt% MgO. For a discussion of the eutectlo reference may be had to WO 00/73231 which document Is hereby incorporated by reference.

O The value of the 81OdRO ratio can be manipulated by changing the amount 0' of 8102 end/or RO to produce a glass composition having a AT as close as possible to the minimum desire AT. A decrease in the value of SiO/RO, which is indicative of o a reduction In the wt% of S102 and/or an increase in the wt% of CaO and/or MgO, or any change or combination of changes In the wt% of the SiOC, CaO and/or MgO, will effect the melt viscosity and AT, and will Increase the crystallizatlon potential.

Conversely. an increase in the value of SIO/RO will effect the melt viscosity and AT, and will decrease the crystallization potential. It should be appreciated that if the value of 8iOz/RO ratio drops too low, AT can drop to an unacceptable level.

Although not required, in one nonllmitlng embodiment of the present invention, SIOR81O is no greater than 2.40. In other nonlimiting embodiments, SIOd/RO is no greater than 2.35. or no greater than 2.30, or no greater than 2.25, or no greater than 2.20. In still another nonlimiting embodiment of the invention, the value of SiO/RO ranges from 1.9 to 2.55, e.g. from 2.1 to 2.55 for boron-free glasses and from 1.9 to 2,4 for boron containing glasses.

In addition to the SiO2 level and the SiOa/RO ratio, the following parameters also describe the compositional envelope level of a quaterary glass composition: the 310/CaO ratio, the SiOdAlaO, ratio, the AIhO1CaO ratio, the sum of SiOz A1209, the diference between SiO, RO, and the AI 2 OsRO ratio. The following parameters describe the compositional envelope level of a glass composition containing additional temperature modifying ingredients: the sum of R20 RO BaO,, where R20 NazO 0 LiO and the (8iO3 AI20)/(R20 RO B0s,) mrio.

While the SIQ/RO ratio at a given sillca level describes the compositional effect of RO on the crystallization potential and melt fluidity, the SIOCaO ratio shows only the effect of CaO an the crystallization potential. If the MgO and the SiO2 levels are kept constant in a comparison of various melts, a decrease In the COMS ID No: SBMI-05827336 Received by IP Australia: Time 17:25 Date 2007-01-05 05/01 2007 16'.36 FAX COLLISON CO IP AUST CANBERRA a019/088 11 0 value of SIOaCaO will show an Increase In crystallization potential due to the contribution of CaO and visa versa. The SiO2 RO difference serves as a similar indicator, i.e. a decrease in the difference or a smaller difference is typically indioative Sof a greater relative amount of RO and thus an Increase in the crystallzation potential. And conversely, an Increase in the difference or a larger difference in RO is indicative of a reduction In the crystaglzatlon potential. In one nonllmiting o embodiment of the present Invention, the SiOa/CaO ratio of the glass composition o ranges from 2.1 to 2.8, e,g. from 2.3 to 2.8 for boron-free glasses and from 2.2 to 2.7 o for boron containing glasses. In another nonllmltng embodiment of the present 17 10 invention, the SIOs RO difference of the glass composition ranges from 26.5 to 36.6 o wt%, e.g. from 30.5 to 38.6 wt% for boron-free glasses and from 26.5 to 34.0 wt% for Cl boron containing glasses.

The sum of SiO2 A2O Ie another parameter that describes the is compositional envelope of a given melt. Up to about an AI,0 level of 14 to 15 wt%, AIzOa Is believed to be able to participate in the network formation with S102, and counteract the crystallization potential of RO that Is always present. At higher AlJOa levels, e.g. greater than 15 wt%, Al0Os will begin to act much like RO and contribute to a rise of the crystallization potential of a given melt. Thus a lower value of SiOa AIO,, which Is Indicative of a lower Al*Oa level for a glass composition of a given wt% of SlIO, will typically result in a lower crystallization potential, and a greater value of SiO, AlaO will typically result In a higher crystallization potential for a given melt. In one nonllmiting embodiment of the present invention, the SiO, A1 2 0 sum of the glass composition ranges from 66.0 to 73.7 wt%, e.g. from 70.8 to 73.7 wt% for boron-free glasses and from 88.0 to 72.1 wt% for boron containing glasses.

Similarly with respect to SIO/AiO0 and based on the characteristics of the melt provided by the amount of AlaOs, an increasing ratio value would be Indicative of a reduction In the amount of AlO 3 and/or an Increase In the amount of SiO2 and would be accompanied by a reduction in the crystallization potential of the melt.

Conversely, a decreasing ratio value would be accompanied by an increase In the crystallization potential of the melt. In one nonlmiting embodiment of the present invention, the SiOs/AlIOs ratio ofthe glass composition ranges from 3.7 to 5.0, e.g.

from 4.2 to 5.0 for boron-free glasses and from 3.7 to 4.9 for boron containing glasses.

In o one nonlimiting embodiment of the present invention, the value of the AhOdCaO Sratio of the glass composition ranges from 0.5 to 0.6. In another nonlimiting embodiment of the present invention, the value of the AlO/RO ratio of the glass Scomposition ranges from 0.4 to 0.e, e.g. from 0.48 to 0.53 for boron-free glasses and Sfrom 0.48 to 0.56 for boron containing glasses. In still another nonlimiting o embodiment of the present invention, the value of the (810 A 2 0)/(R20 RO B2O) ratio of the glass composition ranges from 2.0 to 3.0, e.g. from 2.3 to 3.0 for o boron-free glasses and from 2.0 to 2.7 for boron containing glasses. Reference may C be had to WO 01/32576 for additional discussion on the AlOs/CaO ratio, and the (SiO Aa0 3 )/(R20 RO B13C) ratio.

The discussion will now be directed to additives to the batch materials to alter the forming temperature, the liquldus temperature and the delta T. As previously discussed, boron is a material that is added to glass fiber composlt[ons ao reduce the forming temperature and the liquidue temperature. However, as discussed earlier, the inclusion of boron oxide results in the production of particulate emissions that, depending on the particulate level, may have to be removed from a melting furnace exhaust stream before being released into the environment. Although the amount of can be as high as 10 wt% In an E-glaas Composition, in the present invention, the glass composition has no boron or a low boron content, I.e. has a BO23 content in the range of 0 to 5.10 wt%, In other nonllmltlng embodiments of the present invention, the glass fiber composition has no greater than 4 wt%, or no greater than 3 wt%, or no greater than 2 wt% BaOg. In another nonllmllng embodiment of the present invention, the glass composition is boron-free or essentially boron-free. As the term "essentially free" Is used herein, the glass composition does not include an Ingredient purposely added to the glass but found in the glass in trace amounts, In the practice of the Invention, a glass having up to 0.05 wt% B2Oa is considered a boron free glass.

Further, as previously discussed, fluorine Is a material added to glass fiber compositions as a flux, however, because of the environmental concerns II is preferred not to include fluorine. Nevertheless because equipment is available to remove the fluorine from the exhaust gases, the invention may be praticed using fluorine. In one nonlimiting embodiment of the present invention, the glass COMS ID No: SBMI-05827336 Received by IP Australia: Time 17:25 Date 2007-01-05 05/01 2007 16:37 FAX COLLISON 8& CO IP AUST CANBERRA I021/088 13 0 0 (N composition has low fluorine content, in other words, a fluorine content no greater Sthan 0.30 wt%. In another nonlimiting embodiment, the glass composition is t essentially fluorine free, i.e. It Includes no more than a trace amount of fluorine, which Is considered herein to be up to 0.05 wt%. In still another nonllmiting embodiment, Sthe glass composition does not Include any fluorine. Except where otherwise indicated, the glass fiber forming compositions disclosed and discussed herein are o essentially fluorine free and/or do not include any fluorine.

SAdditional materials that can be added to the glass fiber composition to modify the melt properties, e.g. to reduce forming temperature and/or liquldus temperature of the glas include without limiting the glass compositions disclosed N herein, are .U20, NaO, ZnO, T11s, MnO and/or MnO2. Alkali oxides are network tenminators and tend to effect the melt properties. KaO an alkali oxide is found In levels up to 0.60 wt% in commercial days and is not normally added as a separate Ingredient to the batch materials; however, in the practice of the invention it may be added as a separate material. In the practice of the invention alkali oxides up to 2.00 wt%, preferably 1 wt% are present in the glass of one embodiment of the invention.

In the instance where K2O is present in the clay, the difference is usually made up by additions of Na 2 O and Li 2 0. Li0 is more effective n reducing the melt propertles than NazO. In one non-limiting embodiment of the present Invention, the glass composition Includes 0 to 1.0 wt% U$O and/or 0 to 1.00 wt% NasO and/or 0 to I wt% KzO. Non-alkali oxide ingredients usually employed to reduce the melt properties are ZnO, TIo0, MnO and/or MnO, in amounts of about 0 to 1.5 wt% ZnO, 0 to wt% rTiO, 0 to 3 wt% MnO and/or 0 to 3 wt% MnO. It is believed that levels of these materials less than 0.05 wt% would be considered either tramp amounts or so low that they will not materially impact the glass melt properties. As a resul, in another non-limJting embodiment, 0.05 to 1.5 wt% LisO and/or 0.05 to 1-0 wt% Naa0 and/or 0.05 to 1.0 wt% K0O and/or 0.05 to 1.6 wt% ZnO and/or 0.05 to 1.5 wt% TiOa and/or 0.05 to 3 wt% MnO and/or 0.05 to 3 wt% MnO 2 are Included in the glass composition.

3o In still another nonlimlting embodiment of the invention, the glaes composition includes 0.2 to 1 wt% LiO 2 and/or 0.30 to 1.0 wt% Na 2 O and/or 0.30 to 1.0 wt% KO0 and/or 0.2 to 1 wt% ZnO and/or 0.05 to 1.1 wt% rTi, and/or up to 1 wt% MnO and/or up to 1 wt% 1Q2.

As mentioned above, the ratio (810S Al 2 0)/(R20 RO BZOa) takes into account the wt% of the additlons of 8203, NasO, K0O end Li0 that Is (are) measured In the glass or batch materials regardless of the amount. Tramp amounts of these COMS ID No: SBMI-05827336 Received by IP Australia: Time 17:25 Date 2007-01-05 05/01 2007 16'.37 FAX COLLISON CO IP AUST CANBERRA 022/088 14 0 0 materials in the glass and/or batch are to be used to determine the value of the ratio.

If any or all of the additions of B2Oa, Na2O, O20 and Li~ are not determined to be present In the glass and/or batch, the value of zero is used for that Ingredient In o determining the value of the ratio. For example but not limiting to the invention, if Na,0 K0O and L0O are present and BOa Is not, the ratio (SiO AlO)/(R20 RO SO0,) becomes (SlOa AIOa)/(R20 RO). If none of the ingredients BOs, NaSO, SKaO and LisO are determined to be present, the ratio becomes (SO10 Al 2 OsRO. In o the claims when the ratio (SiO AI20s(R20 RO l920) Is recited in a claim, if Sthe Ingredient is not recited In the claim, it is not used to determine the value of the to ratio even though It Is determined to be present in a glass covered by the claim. The Spreceding discussion Is applicable to the other mathematical relationships, e.g. but Ci not limiting thereto (R20 RO t BOa), It should be appreciated that glass fiber compositions can include other oxides that are present as tramp materials such as BaO, ZrO2, SrO and Cr0A, which are usually present In amounts of up to 0. wt%.

Further, it should be appreciated that the glass compositions disclosed herein can also include small amounts of other materials, for example melting and refining aids, tramp materials or Impurities. For example and without limiting the present invention, melting and fining aids, such as FeO, Fe.A0 and SO,, are useful during production of the glass, but their residual amounts in the glass can vary and typically have minimal, if any, material effect on the properties of the glass product. In addition, small amounts of the additives discussed above can enter the glass composition as tramp materials or Impurities included in the raw materials of the main constltuente, e.g. 0 to 0,5 wt% for SO.s FeO and Fe 3 Os.

Shown In Table 1 are several examples of glass compositions of an embodiment of the invention, which relates to the use of day having high K20 and low TiO 2 levels In glass batch materials and to glass compositions having high levels KaD and low levels of TiO., KaO and TIO can be added to the batch materials but are not economically removed from the days used as batch material. As can be appreciated by those skilled in the art of glass melting and as discussed above, high KO levels, e.g. up to 0.70wt% In the glass raises the forming temperature by as much as about 7 to 10 C In relation to a glass made from clay that introduces 0.10 wt% Ka. One embodiment of the present invention relates to an Improved Etype glass having low weight percent BaOs, a forming temperature no greater than COMS ID No: SBMI-05827336 Received by IP Australia: Time 17:25 Date 2007-01-05 05/01 2007 18:37 FAX COLLISON CO IP AUST CANBERRA a023/088 1230 preferably no greater than 1222 0 C and a delta T of at least 50 °C and preferably up to 65SC. The following are the main constituents in wt% based on the total weight percent of the final glass composition. The KO and TnO112 lted in the ranges below for commercial glasses may or may not be added to the batch as separate ingredient. If the KKO and TfO are not added, it is expected that they would be present in the clay In varying wt% depending on the geographical locatlon of the clay. Although the KGO and 1TiO would be present in the cay, the invention contemplate separate additions of KO0 and/or TiOa to be within the ranges listed below.

In those instances when the clay has high wt% of K0, e.g. 0.60 wt%, it Is necessary to counteract the effect of the K0. More particularly, the KaO increases the forming temperature; therefore, the ingredients In the batch materials have to be modified so as to maintain a low forming temperature, e.g. below 12400C. In one embodiment of the invention such a glass Is as follows.

The experimental or laboratory examples or samples on Table 1 discussed above and on Tables 2 to 19 to be discussed below, unless indicated otherwise, were prepared from certified or reagent grade oxides pure silica or calcia).

Examples F and G on Table 1 and examples H and I on Table 2 are Illustrative examples and were not prepared in the following manner. The batch size for each example was 1000 grams. The individual batch ingredients were weighed out, combined and placed in a tightly sealed glass jar or plastic container. The sealed jar or container was then placed in a paint shaker for 15 minutes or in a tubular mixer for minutes to effectively mix the ingredients. A portion of the batch was then placed into a platinum crucible, filling no more than 3/4 of its volume. The crucible was then placed in a furnace and heated at 1427"C (2600F) for 15 minutes. The remaining batch was then added to the hot crucible and heated at 14270C (2600 F) for 15 to minutes. The furnace temperature was then raised to 1482"C (2700"F) and held COMS ID No: SBMI-05827336 Received by IP Australia: Time 17:25 Date 2007-01-05 05/01 2007 16.'38 FAX COLLISON CO IP AUST CANBERRA l027/088 19 0 0 there for 2 hours. The molten glass was then fritted in water and dried. The fritted ct samples were reheated to a temperature of 14821C (27006F) and held at that temperature for 2 hours. The molten glass was then fritted again In water and dried.

0 The forming temperature, I.e. the glass temperature at a viscosity of 1000 poise, was determined by ASTM method C965-81, and the ilquidus temperature by O ASTM method C829-81. The log 3 forming temperature of the composlUons reported o In Tables 1-20 were determined by a comparison of the glass against physical o standards supplied bythe National Institute of Standards and Testing (NIST). In the Tables, the majority of the reported log 3 forming temperatures is based on o comparison to NIST 710A. Several of the reported log 3 forming temperatures are iN originally based on NIST 717A which uses a borosllcate standard; in those instances the values were converted to correspond to NIST 710A. Therefore all the log3 forming temperatures are considered to based on NIST 710A.

Selected samples had ingredients added that would be found in the clays used in the batch material. Such as lKO, T12, calcium fluoride, SrO and/or CGrOs.

The weight percent of the constituents of the compositions shown in Tables 1- 19 except for Examples F to I are based on the weight percent of each constituent In the batch. It Is believed that the batch weight percent is generally about the same as the weight percent of the melted sample, except for glass batch materials that volatilize during melting, e.g. boron, fluorine and moisture absorbing materials. In the case of boron, it is believed that the weight percent of BaO. in a laboratory sample will be 10 to 16 weight percent less than the weight percent of BaOa in the batch composition, the precise loss depending on the composition and melting conditions.

In the case of fluorine, it is believed that the weight percent of fluorine in a laboratory test sample will be about 50 percent less than the weight percent of fluorine in the batch composition, the precise loss depending on the composition and melting conditions, In the case of CaO, CaO has an certified ignition loss 3-6wt% (an average of 4wt%). The determination of the wt% of the batch materials for the samples listed on Tables 1-19 except for Examples F to I, through an oversight, did not take into account the ignition loss. Therefore in practicing the invention, this fact should be taken into account. Because the 4wt% error is minimal, the recitation of the wt% of CaO recited in the claims covering the embodiments of the glass compositions listed on Tables 1 -19 does not take into account the Ignition loss.

o As can be appreciated by those skilled in the art of converting data from laboratory melt sample to data used to prepare batch materials for commerclal glass production, the melting and fining conditions of the commercial furnace to be used to melat and fine the glass has to be taken into conaideratlon. It is believed that glass o fiber compositions made from ommercial grade materials and melted under Sconventional operating conditions will have similar batch and melt weight percents as discussed above, with the precise loss depending, in part, on the furnace operating Stemperature, through-put and quality of commercial batch materials. The amount of Cl boron and fluorine reported in the tables takes into consideration the expected lose of these materials and represents the expected amount of the material In the glass composition. It should further be appreciated that the glas compositione disclosed herein can also include small amounts of other materials, for example melting and refining aids. tramp materials or impurites. For example and without limiting the present Invention, melting and fining aids, such as 500 are useful during production of the glass, but their residual amounts in the glass can vary and have no material effect on the properties of the glass product. In addition, small amounts of the additives discussed above can enter the glass composition as tramp materials or impurities included In the raw materials of the main constituents.

With reference to Tables 1-20, In each column of each Table, the upper portion of the column lists the wt% of the ingredients in the glass composition based on the batch materials as was discussed above. The middle portion of the column lists the mathematical relationship of the ingredients discussed above for the particular glass compoetion in the same column to obtain the thermal properties listed in the bottom portion of the column e.g. forming temperature, liquidus temperature and delta T (except for certain compositions of Table 20 which Is discussed below.) Table 20 lIsts production glasses. The amount of each constituent of the commercial compositions shown in the Table 20 is the weight percent in the glass. The weight percent for the BaOs was determined using Neutron Transmission analysis techniques and the weight percent for the remaining constituents was determined using X-ray fluorescence analysis (also referred to as XRF analysis'), all of which are well known to those skilled in the art.
