Electrical conductivity of NaF-AlF^sub 3^-CaF^sub 2^-Al^sub 2^O3 melts

The electrical conductivity of NaF-AlF^sub 3^-Al^sub 2^O3 melts with a CaF^sub 2^ concentration of 5 wt % is measured at a continuously varying cell constant when the molar cryolitic ratio CR = [NaF]/[AlF^sub 3^] changes from 1.2 to 2.0 [1, 2]. The experimental data are used to obtain a regression equation to describe the dependence of the electrical conductivity of the melts under study on CR, the alumina content, and temperature {χ] = f(CR, [Al^sub 2^O3], T)}.[PUBLICATION ABSTRACT]
