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 7):
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, the electrode material being prepared by:\n mixing a Cr powder with a solid solution powder of the heat-resistant element and Cr, the solid solution powder being free from a peak corresponding to Cr element in an X-ray diffraction measurement, thereby obtaining a mixed powder; shaping the mixed powder into a shaped mixed powder; sintering the shaped mixed powder, thereby obtaining a sintered body; and infiltrating the sintered body with Cu.
