摘　　要：以ZrOCl2.8H2O和(CH2)6N4为原料,利用均匀沉淀法制得了纳米ZrO2,考察了不同反应条件如:反应物原始浓度、反应物配比、不同陈化方式、不同干燥方式、表面活性剂等对粒径大小、粒子形状、均匀度的影响,采用Malvern粒度分布仪、透射电子显微镜和X射线衍射仪等对产品进行了表征,并得出结论:以六次甲基四胺为沉淀剂制备纳米氧化锆,所得粒子粒度较小、均匀性好,而且操作简便,反应速度快。Using ZrOCl2·8H2O and （CH2）6N4 as raw materials, the nano-sized ZrO2 is prepared by homogeneous precipitation method. The influences of reaction concentration and time, raw material ratio, different aging ways, different drying manners and all kinds of additives on particle size, shape and homogeneity are investigated. TG, TEM and XRD are used to characterize the samples. The conclusion is that nano-sized zirconia obtained by this way not only has smaller size particles and good homogeneity but also easily run and react lastly.
