Abstract: A dielectric material for plasma display panels which comprises a lead-free glass powder and, despite this, gives a dielectric layer less apt to yellow, excellent in transparency, and having a coefficient of thermal expansion suitable for glass substrates, and can be burned at a temperature of 600°C or lower. Also provided are a method of forming a dielectric layer and a glass plate for plasma display panels which is formed by that method. The dielectric material for plasma display panels comprises a ZnO/B 2 O 3 -based glass powder, and is characterized in that the glass powder contains substantially no PbO and comprises a glass containing, in terms of mass%, 46-80% ZnO+B 2 O 3 , 0.3-10% TiO 2 , and 0.01-6% CuO+MoO 3 +CeO 2 +MnO 2 +CoO.

Abstract: A dielectric material for plasma display panels which comprises a ZnO-B2O3-SiO2-Bi2O3-R2O lead-free glass powder and which, despite this, gives a highly transparent dielectric layer on a glass substrate having a silver electrode formed thereon. The dielectric layer is less apt to have yellowed and has a coefficient of thermal expansion compatible with the glass substrate. The dielectric material can be burned at 600°C or lower. Also provided are: a method of forming a dielectric layer; a dielectric layer formed from the dielectric material; and a glass plate for plasma display panels which has the dielectric layer. The dielectric material for plasma display panels comprises a glass powder based on ZnO-B2O3-SiO2-Bi2O3-R2O (wherein R2O represents alkali metal oxides comprising Li2O, Na2O, and K2O). It is characterized in that the glass powder contains substantially no PbO and is made of a glass which comprises, in terms of percentage by mass, 45-85% ZnO+B2O3+SiO2, 10-25% Bi2O3, 0.1-10% R2O, and 0.01-0.30% CoO, the R2O/Bi2O3 ratio being 0.05-0.80 by mass.

Abstract: The invention provides a dielectric material for a plasma display panel which can be fired at a low temperature, is less likely to cause warpage in a glass substrate when fired on the glass substrate and can increase the strength of the glass substrate when fired on the glass substrate, and a glass plate for a plasma display panel including a dielectric layer formed using the dielectric material. The dielectric material for a plasma display panel contains ZnO—B2O2—SiO2-based glass powder, and the glass powder contains substantially no PbO and contains, by mole percent, 1% to 20% (both inclusive) ZnO, 26% to 50% (both inclusive) B2O2, 42% (exclusive) to 50% (inclusive) SiO2, and 0.1% to 5% (both inclusive) Bi2O2.

Abstract: PROBLEM TO BE SOLVED: To provide a dielectric material for a plasma display panel which can be calcined under a temperature of 600°C or less, without generating warpage on a glass substrate at calcination, capable of improving strength of the glass substrate, and furthermore, having high transmittance and low permittivity as well as a haze value, and a glass plate for a plasma display panel equipped with the dielectric layer formed by using it. SOLUTION: The dielectric material for the plasma display panel is composed of ZnO-B 2 O 3 -SiO 2 based glass powder, which does not contain PbO substantially, and is composed of the glass containing 1 to 20% of ZnO, 26 to 50% of B 2 O 3 , over 42 to 50% of SiO 2 , and 5 to 20% of Na 2 O+K 2 O in mole percentage, additionally, with a moisture content of the glass powder to be 0.1 to 0.8 mass%.
