摘　　要：建立了用固相反应法制备PZT热释电陶瓷添加剂铌锰酸铅PbMn_(1/2)Nb_(1/2)O_3的方法,制备出了化学和相组成稳定、纯度高的PbMn_(1/2)Nb_(1/2)O_3结晶粉末,方法简便,工艺成熟。对反应条件进行了优化,并对PbMn_(1/2)Nb_(1/2O_3的元素价态、晶形结构等进行了表征。The process of preparation of PbMn_(1/2)Nb_(1/2)O_3 as PZT pyroetectric ceramic additives by solid state reaction was presented in this paper. The PbMn_(1/2)Nb_(1/2)O_3 powder prepared was proved to have a stable chemical and phase composition and high purity. The optimum conditions for the preparation, the valence states of elements in PbMn_(1/2)Nb_(1/2)O_3 and the crystal structure were studied thoroughly and characterized. The method and technology was quite simple and the preparation process was easy to monitor.
