Abstract:Phase diagrams of K2TaF7-NaCl, K2TaF7-KCl and K2TaF7-NaCl-KCl systems were analyzed in detail. Homologous relations between K2TaF7-alkali halide systems and the technical parameters have been put forward, and influence of alkali halide additions on the specific capacity of Ta powder has been studied.
Key words: K2TaF7 diluent phase diagram molten salt system Ta powder specific capacity
