СПОСОБ ПОЛУЧЕНИЯ ПОРОШКОВ ПЛАТИНОВЫХ МЕТАЛЛОВ И ИХ СПЛАВОВ

摘要

FIELD: chemical and microelectronic industry. ^ SUBSTANCE: invention relates to method for production of powder platinum-group metals and alloys thereof by electrochemical deposition of metal powders from melt salts. Process in the first stage is carried out under galvanostatic conditions in chloride eutectic melt of formula NaCl-KCl-CsCl in ratio of platinum metal ion concentration (mass %) to predetermined current density (A/cm2) from 3.0 to 20 for such period of time as to obtain maximum potential, then electrolysis is carried out under controlled potential conditions. ^ EFFECT: method for production of powders of different structure type and in necessary amount. ^ 4 ex
