METHOD FOR OBTAINING ALUMINUM-SILICON ALLOY AND SODIUM-ALUMINUM FLUORIDES IN ELECTROLYZER FOR PRODUCTION OF ALUMINUM Russian patent published in 1995 - IPC

Abstract RU 2047671 C1

FIELD: production of aluminum in electrolyzer. SUBSTANCE: method involves charging sintered mixture of alumina, sodium silicon fluoride and sodium carbonate with content determined by formula recited in Specification. Sodium carbonate used in the process contains at least 80% by weight of particles with size exceeding 160 micron. EFFECT: increased efficiency in extraction of silicon into alloy and yield of liquid electrolyte. 1 cl, 3 tbl
