Abstract:
The investigation of volume properties of molten salts is important from both views; practical view as well as the theoretical one. Density is one of the most important thermodynamic properties of liquids. The knowledge of density of molten salts is needed for concentration calculations at investigation of kinetics of processes running in the electrolytes. Density of electrolyte determines whether the metal after the electrodeposition will be collected at the bottom of electrolytic bath or will be on the electrolyte level. From the density data volume properties can be calculated and volumetric studies are of considerable value in investigation of the structure of liquids. Volume properties and molar volumes, excess molar volumes and partial molar volumes of different fluoride melts especially of tantalum, niobium, zirconium and aluminium are compared in this work. Based on excess partial molar volumes of compounds (so called parameter of compressibility), we have discussed the volume contraction/expansion.
