ABSTRACT:
A silver-metal oxide composite material comprising a silver matrix, (a) from 1 to 20% by weight, in terms of elemental metal, of an oxide of at least one element selected from the group consisting of Sn, Cd, Zn and In and, optionally, (b) an oxide of Mg, Zr, etc. and/or (c) an oxide of Cd, Sb, etc.; the oxides being dispersed in the form of fine particles with a particle size of not more than about 0.1 .mu.m uniformly and being bound to the silver matrix with no space left, and a process for producing the same. The composite material is excellent in physical and chemical strengths at high temperatures. The process can produce the composite product even with thick walls, within a markedly short time in high productivity. The composite material is useful as electrical contact materials and electrode materials for electric welding.
