The Solgel Preparation and Electric Properties of MnO2-doped PbTiO3 Ceramics

Abstract

Abstract: MnO₂-doped PbTiO₃ ceramics was prepared by means of sol-gel method, its density and some electric properties were investigated. The results showed that it was feasible to prepare multicomponent PbTiO₃ sol-gel series with the aid of sol-gel method, the obtained MnO₂-doped PbTiO₃ ceramics showed a high-purity, uniform component, better dense structure, hardly crack, and had good dielectric, piezoelectric, ferroelectric and pyroelectric properties.

Key words: Sol-gel method, doped PbTiO3 ceramics, Dielectric, Piezoelectric, Ferroelectric, Pyroelectric
