Zusammenfassung:	本发明涉及制备一种以非贵金属氧化物细小颗粒弥散硬化的不含金的铂材，其中非贵金属或者是含量为0.01-0.5重量％的钪，或者是由钪和元素锆、钇、铈中的至少一种金属的混合物/合金，该混合物/合金中的非贵金属总含量为0.05-0.5重量％。 Platinum material contains 0.01-0.5 wt.% scandium or a mixture/alloy of scandium and a either Zr, Y or Ce with a base metal content of 0.05-0.5 wt.%. An Independent claim is also included for a process for the production of a platinum material comprising melting the platinum-base metal alloy, casting and heat treating. Preferred Features: At least 75 wt.% of the base metal is present as an oxide.
