Abstract

Disclosed is an oxide-dispersed platinum material which can be stably used at high temperatures and has excellent weldability. Specifically disclosed is a platinum material reinforced with dispersed oxide wherein particles composed of an oxide of an additional metal are dispersed in a platinum or platinum alloy matrix. Such a platinum material is characterized in that the oxygen concentration in the material excluding oxygen bonded to the additional metal is not more than 100 ppm. The dispersed particles preferably have an average particle diameter of not more than 0.2 µm and an average interparticle distance of 0.01-2.7 µm. The concentration of the dispersed particles is preferably 0.01-0.5% by weight, and the oxidation ratio of the additional metal is preferably 50-100%.
