PROCESS OF PREPARATION OF MIXTURE TO GROW MONOCRYSTALS OF GALLOSILICATES WITH STRUCTURE OF CALCIUM GALLOGERMANATE Russian patent published in 2002 - IPC

FIELD: chemistry. SUBSTANCE: invention is related to technology of preparation of mixture to grow new class of well ordered four-component compounds of gallosilicates with structure of calcium gallogermanate (Ca₃Ga₂Ge₄O₁₄). According to invention oxides of elements included in composition of grown monocrystal Ca₃MeGa₃Si₂O₁₄, where Me is niobium or tantalum taken in stoichiometric ratio, are thermally treated during solid-phase synthesis before mixing, this mixture is sintered at temperature amounting to 92-94% of temperature of synthesis of corresponding monocrystals in the course of 4 hours. EFFECT: development of economically profitable process of preparation of mixture in compact rational form ( profiled pellets ) to grow high-quality monocrystals of gallosilicates utilized in piezotechnology. 1 tbl
