摘　　要：纳米技术的出现和发展为制备高性能陶瓷材料提供了一个崭新的途径。为获得性能优良的眩r压电陶瓷。满足水声换能器的应用需要，试验针对化学沉淀法制备PZT超微细粉进行了深入系统地研究。合成了一次颗粒小于10nm、平均粒径40～50nm的PZT超微细粉。检测结果表明，化学沉淀法是制备高性能PZT超微细粉体的合理方法，粉体颗粒细小、活性好、尺寸分布范围窄，适合制备高性能的PZT压电陶瓷。The appearance and development of nanotechnology have provided a new approach for the improvement of properties of ceramics. In order to produce good quality PZT piezoelectric ceramics and satisfy the requirement of hydro-sonic transducer, PZT superfine powder synthesis by chemical precipitation method is investigated systematically in the paper. Superfine powder with 10 nm minimum individual diameter and 40-50 nm average particles diameter has been synthesized. From the test result,it concludes that chemical precipitation method is a suitable method for producing good quality PZT superfine powder, the powder obtained has advantages in size, reactivity and particle narrow size distribution,which is suitable to produce the PZT ceramics.
