摘要：

For this paper, a super-fine compound powder-Ag/SnO2+La2O3+ Bi2O3 has been obtained successfully using the chemical coprecipitation method. And a new contact material-Ag/SnO2+La2O3+Bi2O3 was produced by the powder metallurgy method. Its properties are as follows: the density is 9.75 similar to9.93g/cm(3); the resistivity is 2.31 similar to2.55 mu Omega .cm; the hardness is 880 similar to 985MPa. Its microstructure shows that the fine oxides have a uniform distribution in the silver matrix. The results of make-break capacity and temperature rise testing show that the new material has better ability of anti-arc erosion and lower temperature rise than that of commonly used Ag/CdO.
