【Abstract】 In order to improve the chemical stability of ZF717/295 optical glass, a series of experiments were carried out. Influence of TiO₂ substitution for PbO, Al₂O₃ substitution for SiO₂ in glass composition,addition of bivalence metallic oxide in the glass and mixed alkali effect on chemical stability of the glass is studied and discussed in the paper.some useful results have been obtained in the study.更多还原
