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
