【摘要】 以化学合成法制备纳米级ZrO₂粉体以及Y_<sub>2O₃稳定ZrO₂粉体,加入混合分散剂并使用氨水和无水乙醇洗涤水合氧化锆以减少颗粒团聚.通过透射电镜（TEM）和X射线衍射（XRD）分析,对粉体的颗粒大小和晶相进行了研究.实验结果表明,硬团聚得以减少,在750℃下热分解所得氧化钇稳定氧化锆粉体平均粒径约为50nm。更多还原

【Abstract】 Nanometer ZrO₂ powder and Y₂O₃ stabilized ZrO₂ powder were prepared by chemical method. It was usedin the experiments that Zirconium hydroxide was washed by ammonia and ethanol to break the agglomerate particles.TEM and X-ray diffration have studied particle size and crystal phase of the powder.It is shown that the agglomeratehas reduced obviously, particle with spherical shape and the medium size of powder calcined at 750℃ is below 50nm.更多还原
