摘　　要：用化学共沉淀—凝胶法制备了分别添加0.3mol％Ca、Mn、Mg的2Y—TZP纳米粉末,在常压下进行了等温烧结试验。结果表明,Mn有促进致密化作用;Ca比Mg具有更强的抑制晶粒生长作用;分析指出,同时加入Mn与Ca有可能制备出致密而均匀的纳米陶瓷体。2Y-TZP with 0. 3mol% additives Ca,Mn,Mg nanophase powders were prepared by chemical copreci-pitation-gel method respectively. Specimens were Sintered in air. The results indicate that Mn increase the densification process, and Ca supresses grain growth more effectively than Mg. Based on the experimental results,it is pointed out that if additives Mn and Ca are used together,dense and homogeneous nanophase Ceramics can be obtained.
