FIELD: chemical technology of composite materials based on oxides for growing of single crystals, in particular, of lanthanum-gallium silicate. SUBSTANCE: for producing single crystals of lanthanum-gallium silicate of stoichiometric composition added to mixture of oxides of lanthanum, gallium and silicon is metallic gallium in the preset range of concentration. Then mixture is heated in oxygen-containing medium locally and short and of short duration up to starting of reaction of self-propagating high-temperature synthesis in conditions of combustion. EFFECT: higher efficiency. 3 cl, 1 tbl
