摘　　要：对Bi2O3超细粉体的制备方法、生产工艺和原理进行了综述,对比了各制备方法的优缺点,提出了Bi2O 3超细粉体制备存在的问题和今后发展方向。指出控制晶体粒度的大小和提高产品的均匀性是制备超细Bi2O3粉体的关键问题,必须对制备过程的力学规律和动力学条件进行深入研究。The detailed preparation methods, technological processes and principles of the bismuth trioxide superfine powder were summarized. The deficiencies, developing trend and the research direction of the bismuth trioride superfine powder were pointed out as well. It＇s shown that controlling the crystal size and improving the product homogeneity may be the key problems of preparation of Bi2O3 superfine powder. So the thermodynamic rules and kinetic conditions of preparing process must be researched thoroughly.
