ABSTRACT:
A silver-metal oxide composite material comprising a silver matrix or silver-copper alloy matrix containing 50% by weight or less of copper, (a) from 0.5 to 25% by weight, in terms of elemental metal, of an oxide of at least one element selected from the group consisting of Mg, Al, Zr, Ca, Ce, Be, Th, Sr, Ti, Cr, Hf and Si, and, optionally, (b) from 0.01 to 5% by weight, in terms of elemental metal, of an oxide of at least one element selected from the group consisting of Bi, Pb, Cd, Zn, Sn, Sb, Mn and iron family metals; the oxide of the (a) element and, where present, the oxide of the (b) element being dispersed in the form of fine particles with a particle size of not more than about 0.1 .mu.m uniformly throughout the matrix from the surface to the core thereof; and process of producing the composite material using oxidation under the conditions in which a liquid phase and a solid phase coexist.
