The role of PbO on crystallization in PbO–SrO–TiO2–SiO2 glass

An investigation of the crystallization in the PbO–SrO–TiO2–SiO2 glass system demonstrates that the crystallization temperature of the glass decreases with an increase of the mole fraction of PbO. The second crystalline phase, SrTiO3, was present when the mole fraction of PbO is more than 0.35, and impaired the piezoelectric coefficient of the glass ceramics in the main crystalline phase, Sr2TiSi2O8.
