A process is disclosed for the preparation of metallic products from metal salts admixed with solvent wherein at least one of the metal salt and the solvent is easily reducible. The admixture is heated under hypercritical conditions of temperature and pressure to produce metallic products and a hypercritical fluid. The hypercritical fluid is subsequently removed from the reaction zone and the metallic product is collected. The metallic product includes pure metals selected from the group of silver, gold, platinum, palladium, ruthenium, rhodium, mercury, arsenic, rhenium, tellurium, iridium, osmium, and copper, and alloys and mixtures thereof. The metallic product ordinarily exists as finely divided powders which may be highly porous. |
