Abstract

Platinum powder having a specific surface area of 0.1-1 m2/g., especially suitable for the formation (optionally in admixture with other metals and inorganic binders) of electric leads in printed circuits, is produced by precipitating Pt from an aqueous platinum chloride solution with zinc, then adding HCl to dissolve excess Zn, and separating nitrogen-free platinum powder from the solution.
