Abstract
The effects of SiO2 additions on the dielectric and thermal properties of barium zinc borate (BZB) glass applied as the dielectric layer in plasma display panels were investigated. With increasing SiO2 content, the glass transition temperature and dilatometric softening temperature of BZB glass increased slightly and its thermal expansion coefficient decreased without sacrificing the dielectric properties. Moreover, the addition of SiO2 overcame the critical demerit of BZB glass, i.e. that its crystallization temperature becomes lower than firing temperature with decreasing B2O3 content. The addition of SiO2 to the BZB glass increased the crystallization temperature from 540 to 600°C. Infrared (IR) analysis shows that these changes result from the structural changes in the BZB glass.
