一种ZrO2粉体的制备方法
摘要：
本申请公开了一种ZrO2粉体的制备方法，包括步骤：(1)、将ZrOCl2·H2O分散于乙醇中，然后添加碱性溶液，调节pH＝7.3～7.8；(2)、取出沉淀物采用去离子水清洗，然后加入分散剂；(3)、在150～180℃烘箱中进行热处理18～22小时；(4)、将得到的沉淀物经去离子水和无水乙醇洗涤；(5)、在60～80℃烘箱烘干，获得纯的ZrO2粉体。本发明获得的ZrO2粉体同时存在单斜相和四方相晶相，其结构能在700℃以上环境中保持稳定性。
摘要（英）：

The invention discloses a method for preparing ZrO2 powder. The method comprises the following steps: (2) dispersing ZrOCl2.H2O in ethanol, and adding an alkaline solution to adjust the pH value to 7.3-7.8; (2), taking out the obtained precipitate, cleaning the precipitate with deionized water, and adding a dispersant; (3), carrying out heat treatment in a 150-180 DEG C oven for 18-22 h; (4), washing the obtained precipitate with deionized water and anhydrous ethanol; and (5) drying the washed precipitate in a 60-80 DEG C oven to obtain pure ZrO2 powder. The ZrO2 powder obtained in the invention simultaneously has a monoclinic phase and a tetragonal crystal phase, and the structure of the ZrO2 powder keeps stable in an environment with the temperature being 700 DEG C or more.
