DIELECTRIC MATERIAL FOR PLASMA DISPLAY PANEL

摘要

A dielectric material for plasma display panels which can be burned at a temperature not higher than 600°C without causing a cost increase and which can be inhibited from being yellowed by silver in burning. 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, 2.5-14.5%, excluding 14.5%, Bi2O3, 1-12% R2O, and 0.01-1.5% CuO, the R2O/Bi2O3 ratio being 0.35-5.0 by mass.
