【Abstract】 The researches of BiScO3-based piezoelectric materials are very important because of their excellent properties, especially their high Curie temperature for the uses in high temperatures. In this paper, the high Curie temperature (Tc>400℃) piezoelectric materials and the processing techniques of these materials are summarized and the recent progresses of these materials are overviewed. It is pointed out that the high Curie temperature BiScO3-based piezoelectric materials are being widely studied worldwide with most interest. The future developments of BiScO3-based piezoelectric materials are also suggested.更多还原
