Abstract:
It is an electrode material that is used as an electrode contact of a vacuum interrupter and that contains one or more parts by weight of a heat-resistant element and one part by weight of Cr, the remainder being Cu and an unavoidable impurity. A part of Cr powder and the heat-resistant element powder are mixed together, and this mixed powder is sintered such that a peak corresponding to Cr element disappears in X-ray diffraction measurement. A solid solution powder obtained by pulverizing a sintered body of the heat-resistant element and Cr obtained by the sintering is mixed with the remaining Cr powder, and this mixed powder is shaped and then sintered. A sintered body obtained by this sintering is infiltrated with Cu.

Claim (Index 11):
A method for manufacturing an electrode material containing one or more parts by weight of a heat-resistant element that is at least one element selected from the group consisting of Mo, W, Ta, Nb, V and Zr, and one part by weight of Cr, a remainder of the electrode material being Cu and an unavoidable impurity,\n wherein a heat-resistant element powder is mixed with a Cr powder that contains Cr of a weight less than a weight of Cr contained in the electrode material, thereby obtaining a mixed powder, the mixed powder is sintered to produce a sintered body containing a solid solution of the heat-resistant element and the Cr such that a peak corresponding to Cr element disappears in an X-ray diffraction measurement, the sintered body containing the solid solution of the heat-resistant element and the Cr is pulverized, thereby obtaining a solid solution powder, the solid solution powder is mixed with a Cr powder that contains Cr of a weight obtained by subtracting the weight of the Cr contained in the Cr powder to be mixed with the heat-resistant element powder from the weight of Cr contained in the electrode material, the mixed powder of the solid solution powder and the Cr powder obtained by the mixing is shaped and then sintered, and the sintered body obtained by the sintering is infiltrated with Cu.
