<p>[PROBLEMS] To provide a method for producing a reinforced platinum material, wherein use is made of a platinum alloy powder prepared by melting and spraying, the above material can be produced by easier and simpler working, a high strength in a welded portion can be secured, and the above material exhibiting excellent creeping characteristics at a high temperature can be produced. [MEANS FOR SOLVING PROBLEMS] A method for producing a reinforced platinum material, wherein an organic solvent is added to a platinum alloy powder prepared by melting and spraying, the resulting mixture is subjected to a wet fine pulverization treatment, and the resulting fine platinum alloy powder is subjected to a degasification treatment by heating, followed by a sintering treatment and a forging treatment, which comprises subjecting a sintered product formed by the sintering treatment to an oxidation treatment, and subjecting said resultant sintered product to a compression molding treatment.</p> |
