Abstract

A gold-free platinum material that is dispersion-strengthened by small, finely dispersed particles of base metal oxide. The base metal is either 0.01-0.5 wt. % Sc or a mixture/alloy of Sc and at least one metal from the group consisting of Zr, Y, and Ce with a total base metal content of 0.05-0.5 wt. %.
