摘　　要：本文以钼酸铵、硝酸钙为原料,在170℃下采用溶剂热法在聚四氟乙烯低压反应釜中反应8小时制备了形貌均匀的CaMoO4微米球。通过X射线粉末衍射及场发射扫描电镜对钼酸钙微米材料进行了鉴定及表征。溶剂热法能有效避免CaMoO4被氧化,易于制备高纯度微米材料。In this paper, calcium molybdate micron pellets with uniform morphology were prepared by solvothermal method in polytetrafluoroethylene low-pressure reactor for 8 h at 170 ℃ using ammonium molybdate and calcium nitrate as raw materials. Calcium molybdate micromaterials were identified and characterized by X-ray powder diffraction and field emission scanning electron microscopy. The oxidation of CaMoO4 can be effevtive avoided by employing solvothermal method, and high-purity micromaterials can be easily obtained.
