摘　　要：采用一般化学沉淀法(正向和反向)、均匀沉淀法和水热法来制备纳米氧化锆,研究了制备工艺对ZrO2粒度分布、粒径大小、团聚程度和形貌等的影响,结果表明采用反向沉淀法制备的纳米ZrO2粒子颗粒细小、均匀性好;均匀沉淀法中微波诱导要优于常规加热法,并讨论了添加剂对纳米氧化锆粒子的影响。Nano-zirconia was prepared by chemical precipitation process （positive and reverse ）, homogeneity precipitation method and hydrothermal process in this work. The influence of different techniques on particle size＇, powder reunite and pattern was studied. The conclusion is that nano-zirconia obtained by the reverse chemical precipitation method has smaller size particles and good homogeneity, microwave heating is better than general heating. The influence of the additive on nano-sized ZrO2 powder was disscused.
