Beschreibung
Zusammenfassung:	The present invention provides a method in which a strengthened platinum material can be produced, in which no blisters occur on the surface of the material even after heat treatment of 1,400.degree.C or higher and a metal oxide such as zirconium oxide is finely dispersed, and which has excellent high-temperature creep properties, when the strengthened platinum material is produced using a melt-sprayed platinum alloy powder. The method for producing a strengthened platinum material includes oxidizing a platinum alloy powder obtained by melt-spray, wet-milling the platinum alloy powder by adding an organic solvent, sintering, and forging, wherein the wet-milled platinum alloy fine powder is charged into a heat resistant container and heated to 1,200 to 1,400.degree.C in a vacuum atmosphere to be subjected to degassing.
