Combined with the recent research status of the preparation of silver based contact materials, the traditional preparation methods of Ag-SnO 2 electric contact materials are introduced, such as internal oxidizing alloy powder and powder metallurgy. The application of new technologies in the traditional preparation process are analyzed. Domestic and foreign new preparation methods of silver based contact materials in recent years are summarized. The advantages and disadvantages of these preparation methods are compared and discussed. Finally, on the basis of the existing preparation techniques, the development trend of the preparation technologies of Ag-SnO 2 electric contact materials is prospected.
