With the expansion of the applications field of piezoelectric ceramic,the performance of piezoelectric ceramics is widely explored by researchers as a kind of precision driving device. The basic piezoelectric properties of piezoelectric ceramic materials were introduced,and the new progress of piezoelectric ceramic at home and abroad in recent years was summarized,and a series of modified measures in production practice were proposed in order to make them fully applied in the production. The application on plasma spraying was introduced,and new development trends in the future of piezoelectric ceramic were introduced and discussed.
