| Abstract: | The physicochemical laws of the formation of Fe−Pt and Fe−Au oxalates have been determined. For the first time finely dispersed
Fe−Pt and Fe−Au composite powders have been fabricated by thermal reduction. The physicochemical and biomedical properties
of such powders are investigated. We show that the powders are corrosion-resistant, are almost monodisperse, have a hydrophilic
surface, are nonpyrophoric, are harmless, are bactericidal, and withstand sterilization temperatures. Their magnetic properties
can be controlled during formation.
