Abstract: From the laboratory data of primary crystallization temperature, electrical conductivity and density of aluminum electrolyte, six empirical expressions were established by regression analysis. The composition of electrolyte consists of Na3AlF6-Al2O3 melts with the additives of AlF3, CaF2 and LiF. These six expressions are comparatively concise and reliable and they are useful for the aluminum metallurgical research work and industrial production.
