Experimental data were presented concerning the density, molar volume and conductivity of NaF–NaCl–WO3 melts. The conductivity of the melts varied linearly with temperature. The molar volume and density increased with increasing WO3 content, and this was attributed to the formation of complex ions which contained W as a complexing agent.
