This is an ultraviolet absorbing colored glass in which 3 to 15% by weight of the Fe content converted into 3 is Fe 2+ .
【０００６】上記成分の限定理由を以下に述べる。Ｓｉ
Ｏ2 の含有量が６５重量％より少ないと耐候性が悪くな
り、７５重量％より多いと失透しやすい。The reasons for limiting the above components will be described below. Si
If the O 2 content is less than 65% by weight, the weather resistance will be poor, and if it exceeds 75% by weight, devitrification is likely to occur.
【０００７】Ａｌ2 Ｏ3 の含有量が０．１重量％より少
ないと耐水性が低下し、５重量％より多いと溶解性が低
下する。When the content of Al 2 O 3 is less than 0.1% by weight, water resistance is lowered, and when it is more than 5% by weight, solubility is lowered.
【０００８】Ｎａ2 Ｏ、Ｋ2 Ｏは原料の溶解を促進する
成分であり、Ｎａ2 Ｏの含有量が１０重量％より少ない
とその効果が小さく、１８重量％より多いと耐候性が悪
くなる。また、Ｋ2 Ｏの含有量が５重量％より多いとコ
ストが高くなる。Na 2 O and K 2 O are components that accelerate the dissolution of the raw materials. If the content of Na 2 O is less than 10% by weight, the effect is small, and if it is more than 18% by weight, the weather resistance deteriorates. . If the content of K 2 O is more than 5% by weight, the cost will be high.
【０００９】ＣａＯ、ＭｇＯは原料の溶解を促進し耐候

失透しやすくなる。ＭｇＯの含有量が１重量％より少な
いと上述の効果が得られず、６重量％より多いと失透し
やすくなる。CaO and MgO are components that accelerate the dissolution of the raw materials and improve the weather resistance. When the content of CaO is less than 5% by weight, the above-mentioned effect is small, and when it is more than 15% by weight, devitrification is likely to occur. If the content of MgO is less than 1% by weight, the above effect cannot be obtained, and if it is more than 6% by weight, devitrification tends to occur.
【００１０】ＳＯ3 は清澄剤である。ＳＯ3 の含有量が
０．０５重量％より少ないと清澄効果がなく、１．０重
量％より多いとＳＯ2 の気泡がガラス中に残存する。SO 3 is a fining agent. If the SO 3 content is less than 0.05% by weight, there is no clarification effect, and if it is more than 1.0% by weight, bubbles of SO 2 remain in the glass.
【００１１】ＣｅＯ2 換算したＣｅ分には主としてＣｅ

収の効果を持たせることができる。The Ce component converted to CeO 2 is mainly composed of Ce.
There are 3+ and Ce 4+ , both of which are components having an ultraviolet absorbing effect. If the Ce content calculated as CeO 2 is less than 0.2% by weight, the effect is small, and if it is more than 1.5% by weight, the effect of absorption of visible light becomes large. Moreover, since Ce having absorption in the near-ultraviolet region is Ce 3+ , CeO 2 is added to T
By reducing with i 2 O 3 , it is possible to further enhance the effect of absorbing near ultraviolet rays.
【００１２】ＴｉＯ2 換算したＴｉ分は必須成分ではな
いが、含有することにより紫外線吸収能を増大すること
ができる。ＴｉＯ2 換算したＴｉ分の含有量が１．０重
量％より多いと主波長が長くなり黄色の着色を生じる。Although the Ti content calculated as TiO 2 is not an essential component, its inclusion can increase the ultraviolet absorption capacity. If the Ti content in terms of TiO 2 is more than 1.0% by weight, the dominant wavelength becomes long and yellow coloring occurs.

る。In addition to the above components, the following trace components are contained. That is, this glass has a brown color, CoO 0 to 0.0015% by weight, Fe content converted to Fe 2 O 3 0.2 to 0.4% by weight, Se 0.00
02-0.0012 wt% and Fe 2 O 3
Of the converted Fe content, 3 to 15% by weight is Fe 2+ .
【００１４】ＣｏＯの含有量が、０．００１５重量％よ

ラスが得られない。If the content of CoO is more than 0.0015% by weight, the dominant wavelength becomes too short and a glass exhibiting a brown color cannot be obtained.
【００１５】Ｆｅ2 Ｏ3 の含有量が０．２重量％より少

％より多いと、Ｓｅの揮散が多くなり、ブラウン色が得
られない。Of the total Fe content expressed as Fe 2 O 3 , FeO, that is, Fe 2+, is in the range of 3 to 15% by weight. Fe exists in the glass in the state of Fe 2+ and Fe 3+ , but the one existing in the state of Fe 3+ has an absorption band in the near-ultraviolet region and is a component that absorbs ultraviolet rays. When Fe 2+ is less than 3% by weight in the total Fe content, Se is oxidized and a brown color cannot be obtained. On the other hand, when Fe 2+ is more than 15% by weight, the volatilization of Se is increased and a brown color cannot be obtained.
【００１７】上記組成範囲のうち、標準光源Ｃにより測

するので、建築用等として特に好ましい。In the above composition range, the dominant wavelength measured by the standard light source C is 488 to 492 nm, and the color purity is 4
A brown glass having a content of ˜6% is particularly preferable for architectural purposes, etc., because it has an excellent ability to absorb ultraviolet rays and exhibits the same color tone as that of conventionally used glass.

ラスと同じ色調であるからである。Furthermore, having the above-mentioned dominant wavelength and color purity,
A glass having a thickness of 3 to 5 mm, which has a visible light transmittance of 70% or more measured by the standard light source A and an ultraviolet transmittance of 15% or less specified by ISO, is particularly preferable as a glass for vehicles exhibiting a brown color. The reason is that external objects are easily recognized, the interior is not deteriorated, the weight is light, and the color tone is the same as that of the brown-colored vehicle glass that has been conventionally used.

生ずるものと考えられる。In the present invention, Fe 2 O 3 , CeO 2 and TiO 2 in the soda lime silica system have absorption ability in the ultraviolet region, and are considered to have the effect of reducing the ultraviolet transmittance of the glass.

e 4+ has ultraviolet absorption bands centered at 315 nm and 210 nm, respectively. Further, TiO 2 is the above-mentioned C
It is also known that there is a charge transfer absorption band with Fe 2+ in addition to the reducing action of eO 2 , and it is considered that ultraviolet rays are efficiently absorbed by these phenomena.

By gradually cooling, a glass having the composition (unit: wt%) described in the upper half of Table 1 was obtained. The glass had a brown color. Then, for this glass, Fe 2+ / total Fe [ie Fe 2+ / (Fe 2+ + Fe 3+ )] (unit:
% By weight, visible light transmittance in terms of thickness 5 mm (unit:
%), Solar heat transmittance in 5 mm thickness (unit:%), UV transmittance in 5 mm thickness (unit:%), thickness 5 mm
Converted wavelength 350nm transmittance (unit:%), thickness 5m
The main wavelength (unit: nm) in terms of m and the color purity (unit:%) in terms of thickness of 5 mm were measured, and the results are shown in the lower half of Table 1. Examples 1 to 6 are examples and Example 7 is a comparative example.

で、素地替えも通常操作で可能である。Since the glass of the present invention has a high visible light transmittance and sufficiently absorbs ultraviolet rays, it can prevent deterioration of interior materials and sheets due to ultraviolet rays and prevent sunburn of persons inside. Therefore, it seems to be particularly useful as a window glass for buildings and vehicles. In addition, since it can be colored under the same level of redox conditions as ordinary colored plate glass, the action of a fining agent such as Glauber's salt is also effective. Therefore, it is considered that the conventional glass melting apparatus, for example, the fining action in the float glass manufacturing process can be performed under the same conditions as usual. Also, since the concentration level is the same level as that of ordinary colored flat glass, it is possible to change the substrate by a normal operation.
