摘要

@@Researching in MMSI of physic -chemical properties improving of cryolite-alumina melts are providing togeth er with material production and development means of low-consumable anodes,because the achievement of positive results at this direction is possible in combina tion of following conditions: unique material,electrolyte composition changing and new construction of a cell de velopment.Standard compound of cryolite-alumina melt is not satisfying the main requirements,which are nec essary to long operation of low-consumable anodes.5%-10% KF addition to the electrolyte leads to reduc ing of the temperature of melt liquidus significantly (3.9 ? vol.% KF) ,decrease the acidity of the melt by KF basicity;increase alumina dissolution in melt.By the way,this direction has own interest as theory and practice evolution of aluminium electrolysis.
