Two versions of heterophase sodium-thermic reduction of potassium heptafluorotantalate were studied. One version implies initiation of the reaction in a homogeneous mixture of solid K2TaF7 and sodium flux, and the other, supply of solid K2TaF7 onto the surface of liquid sodium occurring above the molten halides. The surface area of the tantalum powder was correlated with the K2TaF7 particle size. The formation mechanisms for the tantalum powder particles were discussed for different reduction procedures. The conditions for preparation of powders with the specific surface area of ca. 4 m2 g−1 were identified.
