Enthalpy increment measurements on melts in the system KF-K 2 TaF 7 were carried out by drop calorimetry at temperatures between 298 K and 1063, 1103 and 1143 K for selected compositions. Heat capacities of the melted mixtures and enthalpies of mixing have been determined. Careful calorimetric exper

## Abstract The specific conductivity of the molten KF—K2TaF7 system was measured within the temperature range from 1155 K to 1255 K using a two-molybdenum electrode cell. It was found that the addition of up to 10 mass % K2TaF7 caused a decrease of the system specific conductivity.

## Abstract A special form of the LeChatelier-Shreder equation describing the equilibrium between the crystalline phase and the melt in system A-AB in which the substance AB partially dissociates upon melting was applied to systems KF-K3NbF8, K2NbF7-K3NbF8 and to KF-K3TaF8, K2TaF7-K3TaF8 subsystems
