摘　　要：采用固相合成法在1125~1175℃烧结范围内制备了0.15BiScO_(3)-0.85(Pb_(0.88)Bi_(0.08))(Ti^(0.97)Mn_(0.03))O_(3)(BSPT-Mn)高温压电陶瓷。所有样品均为纯相,晶粒尺寸分布符合正态规律,掺杂元素均匀,未发现明显的富集现象。研究表明,在1150℃烧结制备的BSPT-Mn高温压电陶瓷的最大机械品质因数为1500.3,在484.4℃温度下压电常数为289.8 pC/N,压电性能良好。The 0.15BiScO_(3)-0.85(Pb_(0.88)Bi_(0.08))(Ti_(0.97)Mn_(0.03))O_(3)(BSPT-Mn)high-temperature piezoelectric ceramics were prepared by traditional solid-state method in the sintering range of 1125-1175℃.All samples are pure phase,and the distribution of grain sizes follows the normal distribution pattern.The dopant elements are uniform and no significant enrichment phenomenon is observed.The results show that the BSPT-Mn high-temperature piezoelectric ceramic prepared by sintering at 1150℃achieved a maximum mechanical quality factor of 1500.3,and exhibited good piezoelectric properties with dielectric constant d 33 of 289.8 pC/N at a working temperature of 484.4.
