FIELD: crystal growing. SUBSTANCE: charge for growing stoichiometric lanthanum-gallium silicate monocrystals for piezoelectric and laser engineering includes stoichiometric mixture of lanthanum and silicon oxides and gallium metal. Resultant mixture is heated in presence of oxidant to initiate spontaneous high-temperature synthesis. Mixing and heating are conducted in two stages with different content of gallium. EFFECT: improved required characteristics. 3 cl, 1 tbl
