Measuring Electrical Conductivity of Al-Sc Alloy by Application of Continuously Varying Cell Constant Technique
The electrical conductivity of the molten salts of Na3AlF6-LiF-Sc2O3 system with different compositions was measured at different temperatures by the continuously varying cell constant technique.The main influence factors on electrical conductivity were analyzed.Experiment results showed that the technique of the electrical conductivity measurement is accurate and reliable and the results relative error is just 0.67% in comparison with those in relevant literature.With temperature rising,electrolyte conductivity increases at a rate of about 0.03S/cm for 1℃.And we also found that the conductivity increases slightly with the addition of lithium fluoride and adding scandium oxide makes the conductivity decrease slightly and more addition doesnt cause significant effect.It was proved that the technique can measure accurately the electrical conductivity of aluminium electrolyte and other high-temperature molten salts.
