摘　　要：偏铌酸铅是一种重要的钨青铜结构高居里温度功能陶瓷,在高温领域具有很大的应用前景,但其存在压电活性低,难以烧结等问题,这些问题限制了该陶瓷的应用。元素掺杂取代是改性偏铌酸铅陶瓷的研究热点。综述了偏铌酸铅陶瓷的特点以及部分改性后的陶瓷在超声无损检测等领域的应用前景,对用偏铌酸铅陶瓷制作换能器的研究工作具有一定的借鉴意义。Lead metaniobate is an important tungsten and bronze structure with high Curie temperature function ceramic, which has great applications in the field of high temperature. However, the low piezoelectric activity and difficulty in sintering of lead metaniobate limit the application of the ceramic. Substitution by element doping is a hot topic for modified lead metaniobate ceramics. This paper reviews the characteristics of lead partial niobate ceramics and the application prospects of partially modified ceramics in ultrasonic nondestructive testing. It has certain reference significance for the research work of making transducer with lead metaniobate ceramics.
