Abstract

PURPOSE: To obtain an electrical contact material with superior consumption and melt sticking resistances by dispersing a specified amount of Bi-Sn oxide as a principal component, Bi or Sn oxide, In oxide and Cu oxide in Ag matrix.
CONSTITUTION: An Ag-Sn-Bi-In alloy is heated in an oxidizing atmosphere to selectively oxidize the Sn, Bi and In. The formed oxides are composed of Bi2Sn2O7 as a principal component, Bi2O3 or SnO2 and a little In2O3. These metal oxides are contained as follows when converted into metals: 2W5wt% Bi, 2W4wt% Sn and not less than twice as much Sn as Bi and 1.8W5wt% In. 0.016W2wt% Cu may be added and contained as CuO. Thus, an Ag-metal oxide electrical contact material with superior consumption and melt sticking resistances is obtd.
