Structure and Pyroelectric Properties of PbTiO3 Glass-Ceramics by Sol-Gel Process

Abstract

Abstract: PbTiO₃-SiO₂-B₂O₃ glass-ceramics were prepared by the sol-gel process. DTA and Xray diffraction analysis show that the crystallization temperature of PbTiO₃ glass-ceramics is higher than that of PbTiO₃ ceramics. As the glass content increasing, their pyroelectric coefficients are increased, and the pyroelectric coefficients are increased with the increase of sintering temperatures. The temperature dependence of the dielectric constant of PbTiO₃ceramics and PbTiO₃ glassceramics is different obviously.

Key words: PbTiO₃, glass-ceramics, pyroelectric, dielectric
