Abstract:
There is disclosed a method for manufacturing an electrode by pressing and sintering a mixed powder of a solid solution powder of Cr and a heat-resistant element, which contains Cr and the heat-resistant element in a ratio such that Cr is greater than the heat-resistant element by weight, a Cu powder, and a low melting metal powder (Bi, Sn, Se, Pb, etc.). The low melting metal powder of 0.30 weight % to 0.50 weight % is added to a mixed powder of a solid solution powder of Cr and the heat-resistant element and the Cu powder, and then a mixed powder prepared by adding the low melting metal powder is sintered at a temperature of from 1010° C. to 1035° C. As the low melting metal powder, there is used a powder having a median size of from 5 μm to 20 μm.

Claim (Index 1):
A method for manufacturing an electrode material, comprising the steps of:\n sintering a mixed powder containing a Cr powder and a powder of at least one heat-resistant element selected from the group consisting of Mo, W, Ta, Nb, V, and Zr, the mixed powder containing the Cr and the heat-resistant element in a ratio such that the Cr is greater than the heat-resistant element by weight, thereby making a solid solution of the Cr and the heat-resistant element; pulverizing the solid solution of the Cr and the heat-resistant element to obtain a solid solution powder of the Cr and the heat-resistant element, and then classifying the solid solution powder of the Cr and the heat-resistant element such that a volume-based relative particle amount of particles having a particle size of 90 m or less becomes 90% or greater; mixing the classified solid solution powder of the Cr and the heat-resistant element, a Cu powder having a median size of 100 \u03bcm or less, and a low melting metal powder having a median size of from 5 \u03bcm to 20 \u03bcm, the low melting metal powder being at least one selected from the group consisting of Bi, Sn, Se and Pb, such that the electrode material contains 39.80 to 89.73 weight % of the Cu, 7.96 to 47.86 weight % of the Cr, 1.99 to 11.96 weight % of the heat-resistant element, and 0.30 to 0.50 weight % of the low melting metal powder; and sintering a compact prepared by pressing a mixed powder obtained by the mixing step, at a temperature of from 1010\u00b0 C. to 1035\u00b0 C.
