摘　　要：以氧氯化锆和氨水为反应原料、正丁醇为介质在热液条件下进行了合成纳米ZrO2的实验。对合成的ZrO2进行了XRD和SEM表征。结果表明,在150℃和180℃、填充度为75%的醇热实验条件下均能合成晶粒度为纳米级的氧化锆粉体;粉体是由四方相ZrO2和单斜相ZrO2组成的混合物;粉体的形貌为不规则多面体,随着反应时间的延长,晶粒沿棱柱长轴生长;在180℃条件下反应3h,长径比达到6∶1。Nanosized ZrO2 particles are synthesized by 1-butyl-alcohol-thermal method, using ZrOCl2 · 8H2O and NH3 · H2O as raw materials. The nanosized powders are characterized by means of X-ray diffraction （XRD） and scanning electron microscopy （SEM）. The result shows that ZrO2 powders are synthesized on the condition of temperature 150℃ and 180℃, and fill rate 75%. The powders are the mixture of m-ZrO2 and t-ZrO2. The powders have the characteristic appearance of irregular polyhedron. The grains grow along the main axis of prism with the treatment time increasing. The ratio of length to diameter reaches to 6 = 1 on the condition of 180℃ and 3h.
