    摘要: A contact forming material for a vacuum valve or vacuum circuit breaker comprising (a) a conductive material consisting of copper and/or silver, and (b) an arc-proof material consisting of chromium, titanium, zirconium, or an alloy thereof wherein the amount of said arc-proof material present in said conductive material matrix is no more than 0.35% by weight. This contact forming material is produced by a process which comprises the steps of compacting arc-proof material powder into a green compact, sintering said green compact to obtain a skeleton of the arc-proof material, infiltrating the voids of said skeleton with a conductive material, and cooling the infiltrated material. The contact forming material can provide contacts for a vacuum valve or vacuum circuit breaker which has excellent characteristics such as temperature rise characteristic and contact resistance characteristic.
