Title:
DIELECTRIC MATERIAL FOR PLASMA DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2008/015834
Kind Code:
A1
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/B2O3-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+B2O3, 0.3-10% TiO2, and 0.01-6% CuO+MoO3+CeO2+MnO2+CoO.
