Factors affecting calcining temperatures of BZT–BCT ceramics

Abstract

Piezoelectric ceramic 0.48Ba[Zr0.2Ti0.8]O3 – 0.52[Ba0.7Ca0.3]TiO3 (BZT–BCT) with nanostructure was manufactured with traditional ceramic technology. The nanostructure and the sintering aid reduce the calcining temperature from 1250 to 1170 °C and the sintering temperature from 1450 to 1350 °C. The piezoelectric properties of BZT–BCT at the optimal calcining and sintering temperature are discussed in detail.
