METHOD OF PRODUCING COMPLEX SCANDIUM, POTASSIUM, SODIUM AND AMMONIUM CHLORIDE AND EQUIPMENT FOR ITS REALIZATION Russian patent published in 1995 - IPC

FIELD: inorganic chemistry. SUBSTANCE: mixture of scandium, potassium, sodium and ammonium chloride is prepared, loaded into reactor (2). Sodium and potassium chloride is loaded on the surface of chlorides mixture at equimolar ratio at concentration 0.10-0.15 wt.-% with regard to the mixture of scandium, potassium, sodium and ammonium chlorides and heated up to 800-850 C followed by exposition at this temperature. Ammonium chloride is sublimated and entered to condenser (13) supplied with bug (15). Upper conditioned melt part (18) is poured through the holes (8) in tube (7) and siphon (9) to the glass (11) under vacuum which is placed into hermetic capacity (10). EFFECT: improved method of producing. 4 cl, 1 dwg, 1 tbl
