Abstract: The bismuth aluminate (BiAlO3) is a new developed leadfree piezoelectric material with perovskite structure. BiAlO3 has no structural phase transitions between -133℃ and 550℃, which indicates that it is suitable to be applied in high temperature piezoelectric device. In this paper, the research progress and trends on BiAlO3 based ceramics are reviewed with emphases on the theoretical calculation, high pressure synthetic technology and the addition of the second compound. The limitation and problems in the recent works are discussed, and some ideas for further development of BiAlO3 based ceramics are suggested.

Key words: high temperature piezoelectric ceramics, BiAlO3, perovskite structure
