摘　　要：利用压力-热液法制备纳米氧化锆粉体,考察不同温度和压力下的制备工艺条件,以及采用XRD分析经过热处理后粉体的相组成和晶粒的长大倾向.结果表明,制备出的氧化锆粉体平均粒径约15 nm,粉体在600℃、800℃、1 000℃热处理1 h后,晶粒随温度长大趋势较小,抗老化能力较好.In this Paper,the pressure-heated crystal method was applied to the preparation of nano-ZrO2 powder,and the preparation processes with different pressure and temperature were also discussed.At the same time,the XRD analysis has been made for grain growth tendency and phase composition after the aging test.The result showed that the average grain size of nano-ZrO2 was about 15 nm,moreover,after almost 1h of heat treatment in different temperature(600℃,800℃,1 000℃),the grain growth tendency was relatively slo...
