Abstract:

Conductivity of molten mixtures KF-NaF-AlF3 is measured in the whole concentration range of the {[}NaF]/({[}KF] + {[}NaF]) ratio at the cryolite ratio CR = 1.3 and 1.5 in the temperature range from 800A degrees C to liquidus temperature. Replacement of K+ cations by Na+ ones results in a considerable conductivity increase. Alumina solubility rises with temperature and cryolite ratio ({[}KF] + {[}NaF])/{[}AlF3] in the KF-NaF-AlF3 system, and decreases with sodium fluoride content. Regression equations obtained allow calculating alumina solubility and electrical conductivity in the KF-NaF-AlF3 system in the CR range from 1.3 to 3.0 depending on the concentration of the components and temperature.
