Abstract
It is a method for producing an electrode material containing Cu, Cr and a heat-resistant element. A heat-resistant element powder and a Cr powder are mixed together such that the heat-resistant element is less than the Cr by weight. A resulting mixed powder is baked. A resulting sintered body containing a solid solution of the heat-resistant element and the Cr is pulverized, and a resulting solid solution powder is classified, to have a particle size of 200 μm or less. 10-60 parts by weight of the classified solid solution powder and 90-40 parts by weight of a Cu powder are mixed together, followed by sintering to obtain the electrode material. If a low melting metal powder having a median size of 5-40 μm is mixed with a mixed powder of the solid solution powder and the Cu powder, the deposition resistance property is further improved.
