【Abstract】 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 mechanochemical 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.更多还原
