Electroconductivity slurry-electrolyte of the molten system NaF-AlF3-CaF2-Al2O3

Electroconductivity оf the molten system NaF-AlF3-Al2O3 with addition of 5 % wt.CaF2 at molar cryolite ratio (CR) in the range of 1.2 to 2.0 was studied. Empirical equation describing electroconductivity of the molten system Na3AlF6-AlF3-5 % wt. СаF2-Al2O3 as a function of molar cryolite ratio, undissolved alumina (Al2O3) content and temperature was derived on the basis of experimental data: lnƒ =3,53986 + 1,56·10-3·КО - 14,99·10-3·w(Al2O3) -3476,07/T, where CR - molar cryolite ratio, w (Al2O3) - undissolved alumina content, % vol., T- temperature, K.
