METHOD FOR SYNTHESIS OF PURE CRYSTALLINE MATERIALS ON THE BASE OF HIGH-MELTING OXIDES Russian patent published in 1998 - IPC

FIELD: radio engineering, electronics. SUBSTANCE: method involves production of mixture having predetermined stoichiometric composition, briquetting thus prepared mixture and treatment of thus obtained briquettes by high temperature spray of plasma till melt is obtained. Additionally treatment of melt with the help of spray of plasma is carried out, the process takes place till homogeneous product is prepared. During the whole synthesis process distance between cut of the burner and surface of mixture to be treated is controlled. EFFECT: improved efficiency of the method. 2 tbl
