Moreover, ZnO-B of the present invention 2O 3The glass frit end is low because of the specific inductivity of two materials with the composition material of mullite powders, so can form the next door of low specific inductivity (ε is below 10).Just because of this, also can be fit to be used in the next door that requires low specific inductivity.
It is not only can guarantee shape maintains but also can form the material with high permeability next door that plasma display panel of the present invention forms material with the next door.Therefore, be suitable as and be used to make the next door material that does not contain the high plasma display panel of lead and briliancy.
Embodiment
Investigation by the inventor etc. is learnt: when using mullite powders when replacing alumina powder, even using the poor ZnO-B of BaO 2O 3Under the situation at glass frit end, also can form next door with light transmission.Thus, infer that this is because this ZnO-B 2O 3Be that glass has the specific refractory power that ratio aluminum oxide more approaches mullite easily.
Below, be described in detail next door of the present invention and form material.
Plasma display panel of the present invention forms material with the next door and comprises ZnO-B 2O 3Glass frit end and stopping composition powder.Both ratios are ZnO-B 2O 3The glass frit end is that 60～90 quality %, stopping composition powder are 10～40 quality %, is preferably ZnO-B 2O 3The glass frit end is that 60～85 quality %, stopping composition powder are 15～40 quality %, more preferably ZnO-B 2O 3The glass frit end is that 63～84 quality %, stopping composition powder are 16～37 quality %.When (promptly when glass powder for a long time) the shape maintains reduction after a little while of stopping composition powder.On the other hand, be not easy to guarantee sufficient coking property, be difficult to form fine and close next door when the stopping composition powder becomes for a long time (be glass powder after a little while).And the light transmission in the next door that obtains also reduces.
Moreover material of the present invention mainly uses mullite powders as the stopping composition powder.Mullite powders can be used any of the product that burn till of aluminum oxide and silica or electric smelting product, in order to remove foreign matter etc., though the degree of sintering mullite powders not for example 300～1300 ℃, burn till in particularly preferably in 300～1100 ℃ scope also no problem.In addition, in the present invention, also can all use mullite powders, but in the scope of not damaging light transmission, also can use simultaneously with other stopping composition powder as the stopping composition powder.For example, also can import ceramic powder fillers such as aluminum oxide, silica in order to adjust thermal expansivity.And, in order to improve shape maintains, beyond alumina, the silica, also can import ceramic stopping composition such as trichroite.Mullite powders shared ratio in the stopping composition powder is all is 20～100 quality %, be preferably 25～100 quality %, 30～100 quality % more preferably.When the shared ratio of mullite powders hour, the light transmission in the next door that obtains reduces.
50% median size of mullite powders used in the present invention is preferably 0.5～6 μ m, is preferably 0.6～5 μ m especially.When the median size of mullite powders is too small, in the process of supplying with the mashed prod form, be difficult to adjust rheological property, and cost uprises also.On the other hand, when median size becomes big, the tendency of shape maintenance variation is arranged.In addition, also can mix the above mullite of two different kinds of median size with any mixture ratio.Moreover, with regard to the stopping composition powder beyond the mullite,, preferably use the stopping composition powder of 50% median size at 0.5～6 mu m range based on the reason same with mullite.But, because when using titanium dioxide, the light transmission in obvious damage next door is not so should use in the present invention.
ZnO-B used in the present invention 2O 3The glass frit end is to contain ZnO and B 2O 3Glass for major ingredient.Such glass is that for example ZnO content is the above and B of 30 quality % 2O 3Content is the above glass of 15 quality %.Even and be preferably and do not contain BaO or containing the glass that also is no more than the composition of 25 quality % under the situation of BaO.Its reason is to be favourable because compare when the glass of this scope make up with mullite powders on the next door of making light transmission excellence with alumina powder.Moreover, based on cutting down from the such purpose of the PbO of next door material, with PbO be below the 1 quality % for well, be not preferably at all and contain.
With regard to ZnO-B 2O 3Be the preferred group precedent of glass, can enumerate and contain in Quality Percentage that ZnO is 30～60%, B 2O 3Be 15～35%, BaO is 0～25%, SiO 2Be 3～20%, Li 2O is 0.5～6%, Li 2O+Na 2O+K 2O is 1～12% BaO-ZnO-B 2O 3Be glass.Glass with above-mentioned composition can be produced on the next door material that can burn till especially below 600 ℃ under the low temperature about 560 ℃.Below each composition is described.
ZnO is the composition that when reducing softening temperature thermal expansivity is reduced, and its content is 30～60%, is preferably 35～55%, more preferably 37～54%.When ZnO less than 30% the time, can not obtain above-mentioned effect; When greater than 60% the time, in glass, separate out crystallization, can not get fine and close sintered compact.
B 2O 3Be the composition that constitutes the glass skeleton, its content is 15～35%, is preferably 16～33%.Work as B 2O 3Less than 15% o'clock, be difficult to vitrifying; On the other hand, work as B 2O 3Greater than 35% o'clock, it is too high that softening temperature becomes, and when burning till under the temperature below 560 ℃, can not get fine and close sintered compact, and the display panel characteristic also reduces.
BaO is the composition that makes stabilization, and its content is 0～25%, is preferably 3～25%, more preferably 4～23%, is preferably 5～20% especially.BaO is not essential composition, but when less than 3% the time, the glass instability is easy to generate crystallization, has problems with the fitting tightly property of dry film, when forming material as the next door and burn till, thereby can not get the sintered compact of densification because of separating out crystallization.When greater than 25% the time, thermal expansivity uprises, and is not suitable for glass substrate, and light transmission reduces, so not preferred.
SiO 2Be the composition that forms the glass skeleton, its content is 3～20%, is preferably 4～17%, more preferably 4～16%.Work as SiO 2Less than 3% o'clock, the glass instability; When greater than 20% the time, it is too high that softening temperature becomes, and can not burn till under the temperature below 560 ℃.
Li 2O is the significantly reduced composition of softening temperature that makes glass, and its content is 0.2～6%, is preferably 0.5～5%.Work as Li 2O is less than 0.2% o'clock, because fully do not reduce softening temperature, so be difficult to burn till under the temperature below 560 ℃.On the other hand, work as Li 2O was greater than 6% o'clock, and glass is obviously unstable, is easy to generate crystallization, with the fitting tightly property reduction of dry film, when burning till as next door formation material, thereby can not get fine and close sintered compact because of separating out crystallization.
In addition, in order to keep the stability of glass, can not be with Li 2Under the situation of O heavy addition in the glass, preferably use and Li 2Composition---the Na that O equally makes the softening temperature of glass reduce 2O or K 2O or use both simultaneously.But, work as Na 2O, K 2The content of O for a long time, have stability, glass reduce, with the fitting tightly property reduction of dry film, can not get the anxiety of fine and close sintered body, so expectation Na 2O content is limited in below 9%, is preferably below 8%, is preferably below 6% especially, expectation K 2O content is limited in below 6%, is preferably below 5% especially.
With regard to the alkali composition, with Li 2O, Na 2O and K 2The total amount of O is calculated, and to need content be 1～12%, be preferably 2～10%.When the total amount less than 1% the time, because the softening temperature of glass is fully reduced, so can not under the temperature below 560 ℃, burn till.On the other hand, when greater than 12% the time, the glass instability, crystallization has easily reduced the fitting tightly property with dry film, and the weather resistance of glass has problems.
When adding the basic metal composition, the tendency with the fitting tightly property reduction of dry film is arranged.Therefore, in order to improve fitting tightly property, also can contain Al 2O 3But, work as Al 2O 3Contain quantitative change for a long time, softening temperature rises, so be preferably limited to below 1.5%.
Moreover, in order to make stabilizationization, preferred BaO/ (B 2O 3+ SiO 2) ratio in 0.1～0.8 scope.When this ratio less than 0.1 the time, it is unstable that glass becomes, and when forming material as the next door and burn till, is difficult to obtain the sintered compact of densification because of separating out crystallization.In addition, when greater than 0.8 the time, the next door forms the material coefficient of thermal expansion coefficient and uprises, and is difficult to be suitable for glass substrate.Preferred scope is 0.15～0.6.
Moreover, except that above-mentioned composition, in the scope of not damaging effect of the present invention, can add other composition.For example, in order to improve water tolerance or resistance to chemical reagents, can add alkaline earth metal oxide or Ta such as MgO, CaO, SrO 2O 5, La 2O 3, SnO 2, ZrO 2, TiO 2, Nb 2O 5, and, for stabilizationization, also can add P 2O 5In addition, the addition of these compositions is preferably and is limited in below 15%, is preferably below 14%, more preferably below 12%, be preferably below 10% especially to close quantifier.
