Influence of BaO/(SrO + BaO) on some thermal properties of R₂O-RO-SiO₂ glasses for plasma display panel Substrate

Abstract

An influence of BaO/(SrO + BaO) on some thermal properties was studied in alkali - alkaline earth - silica PDP (Plasma Display Panel) Substrate glasses. SrO was replaced progressively by BaO at fixed concentration of alkaline earth oxides. Four viscosity fixed points at low temperature, thermal expansion coefficient and density of glasses were determined. The compositional dependence of those properties was discussed from the viewpoint of the mixed alkaline earth effect and the raw material cost.
