【Abstract】 BiScO₃-PbTiO₃（BSPT） is a new type of piezoelectric material with perovskite structure, which has the advantages of high Curie temperature and high piezoelectric properties, and can be used to build high-performance piezoelectric devices that work in extremely high temperature environments. In this paper, the research advances of BSPT-based materials were reviewed based on our group’s work from the aspects of crystal structure, modification method, and preparation technology. The composition design strategies of different systems and the application of high-temperature piezoelectric devices were emphasized, and their development directions are prospected.更多还原
