Current Development of Piezoelectric Materials with High Curie Temperature

In the energy,aerospace,automobile,metallurgy and petrochemical fields,there existed pressing demands for those piezoelectric devices which could be operated stably and reliably under high temperature.Since the piezoelectric materials with high Curie temperature are the key sense components in the high temperature piezoelectric devices,the study on the piezoelectric materials with high temperature has been attracted more and more attention.In this paper,the structures and properties of different kinds of high temperature piezoelectric materials have been analyzed briefly,the current development of piezoelectric materials with high temperature has been overviewed and the future development as well as the hot-points of piezoelectric materials with high temperature have also been discussed.
