FIELD: metallurgy.
SUBSTANCE: double complex chlorides of ittrium and potassium is reduced by lithium at temperature 450-720°C in inert atmosphere and high pressure. Received reacting mass is heated at a rate 3-5°C/min up to the temperature for 60-300°C higher the reduction temperature and then it is implemented vacuum separation at a temperature 750-780°C and evacuation 1·10-4 millimetres of mercury.
EFFECT: it is provided receiving of microcrystalline metallic powder of itrrium with minimal content of oxygen and gas-producing admixtures, described by high dispersity.
