Abstract :
Phases of aluminum electrolytes with additives of NaCl and KF were investigated. The definition and determination of the cryolite ratio of bath were discussed based on the results of phase composition. The deduced cryolite ratio equation was justified by fluorideion selective electrode analysis (FISEA). Experimental results show that FISEA has good performance with high accuracy and reproducibility for an aluminum bath containing NaCl and KF.
