  • Patent number: 9281136
    Abstract: The electrode material for a vacuum circuit breaker is produced by a method comprising a mixing step, a press sintering step, and a Cu infiltration step. In the mixing step, an Mo powder having a particle diameter of 0.8 to 6 ?m is homogeneously mixed with a thermite Cr powder having a particle diameter of 40 to 300 ?m in such a manner as giving a mixing ratio (Mo:Cr) of 1:1 to 9:1 and satisfying the weight relation Mo?Cr. In the press sintering step, the resultant mixture is pressure molded under a press pressure of 1 to 4 t/cm2 to give a molded article. Next, said molded article is sintered by maintaining the same at a temperature of 1100 to 1200° C. for 1 to 2 hours in an heating furnace to give a partially sintered article. In the Cu infiltration step, a thin Cu plate is placed on said partially sintered article and maintained at a temperature of 1100 to 1200° C. for 1-2 hours in a heating furnace so that Cu is liquid-phase sintered and infiltrated into the partially sintered article.

  • Patent number: 8440112
    Abstract: Atomized Cu—Cr alloy powder, 20 to 30 percent by weight of Thermite Cr powder and 5 percent by weight of electrolytic Cu powder are mixed together and undergo solid phase sintering treatment to form an electrode material for vacuum circuit breakers. The gross content of Cr of the electrode material is 30 to 50 percent by weight. In manufacturing the electrode material for vacuum circuit breakers, such powders are mixed together and then undergo compression molding to be formed into a compressed compact. The compressed compact is performed solid phase sintering at a temperature lower than the melting point of Cu in a non-oxidizing atmosphere to prepare a solid phase sintered body.
