Abstract: 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.
