METHOD FOR PRODUCING ELECTRODE MATERIAL |
| 摘要 |
A method for producing an electrode material, provided to involve: (i) a provisional sintering step of sintering a mixed powder containing a powder of a heat resistant element and a powder of Cr to obtain a solid solution where the heat resistant element and Cr are dissolved; (ii) a pulverizing step of pulverizing the solid solution to obtain a powder; (iii) a main sintering step of sintering a molded body obtained by molding the powder of the solid solution, to produce a sintered body; and (iv) a Cu infiltration step of infiltrating the sintered body with Cu. |

1. A method for producing an electrode material, comprising:
a provisional sintering step of sintering a mixed powder containing a powder of at least one kind of a heat resistant element selected from the group consisting of Mo, W, Ta, Nb, V and Zr and a powder of Cr to obtain a solid solution where the heat resistant element and Cr are dissolved; a pulverizing step of pulverizing the solid solution to obtain a powder; a main sintering step of sintering a molded body obtained by molding the powder of the solid solution, to produce a sintered body; and a Cu infiltration step of infiltrating the sintered body with Cu, wherein in the provisional sintering step the mixed powder is sintered until either a peak corresponding to Cr element or a peak corresponding to the heat resistant element, which are observed by X ray diffraction measurement made on the solid solution, completely disappears. |
