METHOD OF PRODUCING DISPERSION-REINFORCED PLATINUM GROUP METALS AND ALLOYS Russian patent published in 1997 - IPC

FIELD: precious metal metallurgy. SUBSTANCE: in colloid hydroxide solution producing refractory oxide, e.g. zirconium oxide, powders of platinum metal carbonyls, e. g. [Pt(Co)₂]_n, Pt₅Pd(Co)₁₄, Pt₅Ph(Co)₁₆, are slurried. Precipitate is separated and air dried which results in self- inflammation of product and formation of corresponding metal powder or sponge dispersion-reinforced by refractory oxide, e.g. zirconium hydroxide. EFFECT: simplified procedure. 2 cl, 1 tbl
