摘要
铝酸铋(BiAlO3)是近年发现的一种新型钙钛矿结构无铅压电材料,在-133℃到550℃的温度范围内不存在结构相变,适合作为高温压电器件材料使用.本文从理论计算,高压合成工艺和添加第二组元等方面归纳和分析了BiAlO3基无铅陶瓷的研究进展和趋势,评述了现有研究中存在的问题和不足,并对BiAlO3基无铅压电陶瓷今后的研究和发展提出一些建议.
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.
