【Abstract】 The progress in the research of electroless silver plating of powders was reviewed. Thus the methods for the pretreatment of powders subjected to electroless silver plating were briefed. The research and application of the electroless silver plating of metallic powders, inorganic powders, and macromolecular powders were summarized. The stability of the plating solution, the surface catalytic activity of the powders, the dispersaney of the powders in the plating bath, and the uniformity of the electroless Ag coating were highlighted with respect to the electroless silver plating of three kinds of powders. Besides, the directions in the future study of silver plating of powders were suggested as well.更多还原
