摘　　要：用氧化物合成法制备了0.36BiScO3-0.64PbTi O3(BSPT)铁电陶瓷.采用XRD和SEM等分析技术,研究了BSPT陶瓷的结构特点和微观形貌,测试了BSPT陶瓷的介电、压电性能.实验结果表明,利用氧化物合成法可以合成钙钛矿结构的BSPT陶瓷,其钙钛矿相含量最高可达92%以上.SEM分析表明,在1150～1180℃温度范围内烧结得到的BSPT陶瓷晶粒饱满、晶界清晰.BSPT陶瓷随烧结温度的升高,机械品质因数Qm明显增大.The 0.36BiScO_3-0.64PbTiO_3(BSPT) ferroelectric ceramics were synthesized using the conventional oxide process. The structural properties and morphology of the BSPT ceramics were characterized by XRD, SEM analysis techniques. The dielectric and piezoelectric properties of the BSPT ceramics were also measured. The results of XRD showed that the BSPT ceramics with perovskite structure could be prepared by using the conventional oxide process. The highest percent of the perovskite structure of the BSPT ceramic...
