摘要
钛酸铅系陶瓷是一种重要的功能材料,在压电领域应用广泛。该陶瓷存在烧结、极化困难,压电性能低的问题,其烧结和压电性能是目前的研究热点。综述了通过元素掺杂和组元添加对钛酸铅系陶瓷进行改性以改善烧结性能和压电性能的研究现状,以及改性后陶瓷的应用现状。指出了未来的研究方向,包括烧结工艺的优化、元素复合掺杂以及准同型相界区的成分设计等。
Lead titanate series ceramics are important functional materials and are widely used in piezoelectric field. The ceramics are difficult to sinter and polarize, and the piezoelectric property is relatively low. The sintering and piezoelectric properties are research focuses at present. The research status of modifying lead titanate series ceramics by element doping and component addition to improve the sintering property and piezoelectric property, and the application of modified ceramics are reviewed. The future research directions are pointed out, including optimization of sintering process, element composite doping and composition design of quasi-homotype phase boundary.
