摘要： 利用空气等离子体氧化热分解碱式碳酸锆和喷雾法等离子体热分解氯氧化锆水溶液制备超细氧化锆粉体，固相氧化热分解所制氧化锆平均粒径可达0.1 mm左右，晶型为亚稳立方、四方和单斜混晶结构，喷雾法等离子体热分解氯氧化锆水溶液所得氧化锆粉体平均粒径为5~60 nm，亚稳混晶结构. 在反应过程中对等离子体温度进行控制，可得到形貌为球形的微粉产品.

Abstract: Ultrafine ZrO2 particles were prepared by the oxidation-thermal decomposition of Zr2O(CO3)×xH2O and the spray-ICP technique of zirconium salt solution in an inductively coupled plasma. Their particle diameters ranged from 0.1~0.3 mm and 5~60 nm respectively. X-ray diffraction analysis indicated that the major phase is tetragonal and cubic ZrO2, the minor one is monoclinic ZrO2, the major is of metastable structures.

Key words: ultrafine ZrO2, plasma, oxidation-thermal decomposition reaction, preparation, nomoparticles
