Abstract
A material for electric contacts based on silver-tin oxide is obtained by mixing a powder of silver or an alloy mainly containing silver with a powder consisting mainly of tin oxide and 0.01 to 10 wt. % (in relation to the quantity of tin oxide) of an additive consisting of one or more compounds containing silver, oxygen and a metal from sub-groups II to VI of the periodic system and/or antimony, bismuth, germanium, indium and gallium, compacting the mixture and sintering it. The tin oxide may be replaced by zinc oxide.
