| 摘 要： | 以片状Bi_4Ti_3O_(12)粉体为原材料制备了0.1BiYbO_3-0.9PbTiO_3(BYPT)高居里温度压电陶瓷,研究了Bi_4Ti_3O_(12)粉体用量对BYPT陶瓷显微组织结构和压电性能的影响.结果表明,BYPT陶瓷的最佳烧结温度为1 140 ℃,陶瓷由多相组成.BYPT陶瓷的居里温度均大于520 ℃,且随着Bi_4Ti_3O_(12)用量的增加,材料由正常铁电体向弛豫铁电体转变,陶瓷的居里温度、压电常数及介电常数先升高后降低,介电损耗则随之而减小,BYPT_2陶瓷的居里温度和压电常数最高.

| Abstract: | In this paper, piezoelectric ceramics 0.1BiYbO_3-0.9PbTiO_3 (BYPT) with high Curie temperature were prepared by using Bi_4Ti_3O_(12) (BIT) as raw material.The effect of BIT content on the microstructure and electrical properties of BYPT ceramics was investigated. The results showed that the optimized sintering temperature was 1 140 ℃.There were many phases coexisting in the BYPT ceramics with Curie temperatwre higher than 520 ℃.The Curie temperature T_C, the piezoelectric coefficient d_(33) and the dielectric constant ε increased firstly and then decreased with increasing BIT content. The BYPT_2 ceramic had the highest Curie temperature and piezoelectric constant. |
