摘要

Piezoelectric ceramics BiYbO₃-PbTiO₃(BYPT) with high curie temperature were prepared by the conventional solid state reaction. The effect of BiYbO₃ on microstructure and electrical properties was investigated. The result revealed that there were two phases coexisting in the ceramic, one was perovskite phase, the other was Yb₂Ti₂O₇ phase. With increasing BiYbO₃ content, Yb₂Ti₂O₇ phase increased. Curie temperature T_C and dielectric constant ε_r increased and then decreased with increasing BiYbO₃ content, while dielectric loss tan δ showed opposite rule. The BYPT ceramics with 10%BiYbO₃ had the excellent properties, T_C was 590°C, ε_r was 660 and tan δ was 0.017.
