Microwave Sintering of Lead-Free Barium Titanate Piezoelectric Ceramics from Barium Titanate Powders Synthesized by Hydrothermal Method

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.
