Title:
真空遮断器用電極材料及びその製造方法
Document Type and Number:
Japanese Patent JP5124734
Kind Code:
B2
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.
