摘　　要：以ZrOCl2·8H2O和CO(NH2)2为原料,采用低温陈化法制得了纳米ZrO2,考察了不同反应条件,如反应物原始浓度、反应时间、不同反应物配比、表面活性剂等对产物粒径的影响,采用透射电镜、X射线衍射仪、粒度分布仪、红外光谱仪、差热分析仪对产品进行了表征,并得出结论:低温陈化法可以制得纳米级的ZrO2粒子,而且粒子分散性、均匀性较好,并对其机理进行了探讨。Using ZrOCl_2·8H_2O and　CO(NH_2)_2 as raw materials,the nano-sized ZrO_2 was prepared by low-temperature aging. The influences of reaction concentration and time ,raw material ratio and all kinds of addictives were investigated.TEM,XRD ,TG,UV and DTA were used to characterize the samples. The conclusion is that nano-sized zirconia can be obtained by this way. And it has good homogeneity and no hard agglomerates.The mechanism is also researched.
