Abstract

The paper presented a simple and highly effective new way ofmeasuring the electrical conductivity of molten salts—the tube-type cell technique. The electrical conductivity of nNaF·AlF₃-Al₂O₃-CaF₂ melts was measured by impedance meter with pyrolytic boron nitride (BN) as conductivity cell, tungsten filament as the working electrode and graphite as the counter electrode, and was compared with the data of conductivity obtained by CHOUDHARY model and the WANG model. The result shows that the data obtained by tube-type cell are similar with to calculation data by the empirical formula with high-accuracy and high reproducibility, hence , the tube-type cell technique is an effective way of measuring with the excellent properties of high-accuracy, simple structure and inexpensiveness whose application of range can be widen to measure conductivity of molten salts.
