Description:
Silver-tin oxide electrical contact material with 10 wt pct stannic oxide and balance nanosized and micronsized silver was developed successfully. Stannic oxide particles chemically coated by a layer of silver nanospheres are homogeneously dispersed in a silver microcrystalline matrix made by chemical synthesis. The material processed by pressing-sintering-repressing exhibited enhanced properties: density: 97.1 to 97.9 pct relative density, Vickers hardness: 103 to 115, electrical conductivity: 65 to 69 pct IACS, volumetric shrinkage: 28.9 to 30.9 pct, and a very fine and uniform microstructure.
