FIELD: chemistry.
SUBSTANCE: production of complex oxide compounds of rare-earth metals involves preparation of a mixture from rare-earth metal oxide powder, metal powder and an oxygen-containing additive, taken in hyperstoichiometric ratio, putting the mixture onto a substrate and carrying out a combustion reaction. The oxygen-containing additive is perchlorate of an alkali or alkali-earth metal selected from sodium, potassium, lithium, barium, calcium or magnesium, which is first mixed with rare-earth metal oxide powder, with the following ratio of components in wt %: rare-earth metal oxide 65.71-88.06; metal 11.94-34.29; perchlorate of alkali or alkali-earth metal 13.49-24.71.
EFFECT: simple and faster process of obtaining the end product.
