摘　　要：利用传统的固相合成法合成了纯钙钛矿结构的钛酸铋钠基压电陶瓷,研究了不同烧结温度下的钛酸铋钠基压电陶瓷的烧结行为,并对烧结过程中陶瓷表面出现第二相的机制进行了模型分析。最后研究了钛酸铋钠基陶瓷系列的电学性能。（Bi0.5Na0.5）TiO3-based piezoelectric ceramics of single perovskite were synthesized by traditional solid sintering method. We studied the sintering behavior of the ceramics at different temperatures, and analysed the sec-ond phase exited on the surface with a founded mold. At least, the electric properties of the ceramics sintered at dif- ferent temperatures were shown.
