摘　　要：通过超细粉体的表面包覆以改善粉体的分散性及其表面性质,已经成为超细粉体制备和应用的关键技术。综述了超细粉体的表面包覆方法,包括机械化学法、气相沉积法、聚合物包裹法、液相化学法及微胶囊化法等,主要介绍了每种方法的基本原理及应用。Surface coating of superfine powders for the improvement of the dispersion property and surface properties of fine powders have being become the critical technique in the preparation and application of surperfine powders. The main methods of surface coating including mechanoehemical technology,chemistry vapour deposition technique,polymer coatings, hydro-chemical method and microencapsulation technology are described. The basic principle and application of these methods are discussed.
