FIELD: metallurgy.
SUBSTANCE: method for obtaining iridium hydrochloric acid refers to chemical metallurgical production of metals of platinum group (Mill) and their compounds. The technical result of the invention consists in obtaining of the powder of iridium hydrochloric acid with iridium mass % (38-45). The method includes dissolving of hexachloriridate ammonium in chloronitric acid. Then repeated evaporation of the chloride solution is performed with removal of the solvent at a temperature of 100-120°C before foaming of obtained melt of iridium hydrochloric acid and cooling of the obtained product in a dry air or dry inert gas medium.
EFFECT: production of iridium hydrochloric acid powder.
