摘要

In this study,three types of BaTiO3 powders with different particle size synthesized by 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 temperature (1100 and 1150℃) using microwave sintering method,and their piezoelectric properties were investigated and compared.The results indicate that all The BaTiO3 piezoelectric ceramics exhibit higher d33 value (over 330 pC/N,the highest is about 370 pC/N).The reasons were also investigated by comparing the properties of three kinds of BaTiO3 powders,sintering temperature and method.
