Abstract
In this paper, piezoelectric ceramics 0.1BiYbO3-0.9PbTiO3 (BYPT) with high Curie temperature were prepared by using Bi4Ti3O12 (BIT) as raw material. The effect of BIT content on the microstructure and electrical properties of BYPT ceramics was investigated. The results showed that the optimized sintering temperature was 1140°C. There were many phases coexisting in the BYPT ceramics with Curie temperature higher than 520°C. The Curie temperature TC, the piezoelectric coefficient d33 and the dielectric constant ε increased firstly and then decreased with increasing BIT content. The BYPT2 ceramic had the highest Curie temperature and piezoelectric constant.
