摘要：

In this study, three types of BaTiO3 powder with different particle sizes synthesized by a hydrothermal method were used to fabricate the lead-free barium titanate piezoelectric ceramics. The BaTiO3 ceramics from these three types of BaTiO3 powders were sintered at different temperatures (1100 and 1150 degrees C) using a microwave sintering method, and their piezoelectric properties were investigated and compared. The results indicate that all The BaTiO3 piezoelectric ceramics exhibit higher d(33) value (above 330 pC/N, the highest is about 370 pC/N). The reasons were also investigated by comparing the properties of the three types of BaTiO3 powders, sintering temperature and method.
