| Abstract/Summary |
The electrical conductivity of low-melting electrolytes (AlF3-rich, e.g. n(NaF)/n(AlF3) = 1.4, with additives Al2O3 and CaF2) was determined using a pyrolytic BN tube type cell. AC - techniques with a sine wave signal with 10 mV amplitude in the high frequency range were applied. Basic melt contained 58.33 mol% NaF and 41.67 mol% AlF3. To this melt 2 wt% alumina and/or 5 wt% calcium fluoride were added. The electrical conductivity data in the molten system can be described by a simple equation of the Arrhenius type: κ = A e -B /T where κ represents the electrical conductivity (Ω-1 cm-1), T is the temperature (K), A and B are constants for the measured system.
