    摘要： 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 in a ratio such that the heat-resistant element is less than the Cr by weight. A mixed powder of the heat-resistant element powder and the Cr powder is baked. A sintered body obtained by the baking and containing a solid solution of the heat-resistant element and the Cr is pulverized, and a solid solution powder obtained by the pulverizing 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.

    摘要： Disclosed is a vacuum circuit breaker (1) including a vacuum interrupter (3) accommodated in a ground tank (2) filled with insulating gas. At least one of a fixed electrode (10) and a movable electrode (11) of the vacuum interrupter (3) uses an electrode material in which particles containing a solid solution of a heat resistant element and Cr are finely and uniformly dispersed and in which Cu textures as a high conductive component are finely and uniformly dispersed. The electrode material contains 20 to 70% by weight of Cu, 1.5 to 64% by weight of Cr and 6 to 76% by weight of the heat resistant element relative to a weight of the electrode material. The particles of the solid solution in the electrode material have an average particle size of 20 µm or smaller.

    摘要： A method for producing an electrode material wherein particles containing Cr are miniaturized and uniformly dispersed and Cu portions, which serve as a highly conductive component, are also miniaturized and uniformly dispersed. This method for producing an electrode material involves: a mixing step (S1) for mixing a heat resistant element powder and a Cr powder; a provisional sintering step (S2) for obtaining a solid solution of the heat resistant element and Cr by provisionally sintering the mixed powder; a pulverizing step (S3) for obtaining a solid solution powder of the heat resistant element and Cr by pulverizing the solid solution of the heat resistant element and Cr; a molding step (S4) for molding the solid solution powder; a main sintering step (S5) for obtaining a sintered body (skeleton) of the heat resistant element and Cr by subjecting the thus-obtained molded body to main sintering; and a Cu infiltration step (S6) for infiltrating the sintered body of the heat resistant element and Cr with Cu.
