POTASSIUM HEPTAFLUOROTANTALATE(V) Chemical Properties,Usage,Production

Chemical Properties

White, silky needles. Slightly soluble in cold water; quite soluble in hot water.

Chemical Properties

Potassium heptafluorotantalate, K2TaF7, crystallizes in colorless, rhombic needles. It hydrolyzes in boiling water containing no excess of hydrofluoric acid. The solubility of potassium heptafluorotantalate in hydrofluoric acid decreases from 60 g/100 mL at 100 °C to 0.5 g/100 mL at room temperature. The different solubility characteristics of K2TaF7 and K2NbOF5 are the fundamental basis of the Marignac process.

Uses

It is an important raw material. Used in chemical research. Use as primary and secondary intermediate(Pharmaceutical Intermediates). Used in the production and preparation of tantalum powder.

Uses

Intermediate in preparation of pure tantalum.

Hazard

Toxic by inhalation.

Flammability and Explosibility

Non flammable

Safety Profile

Poison by ingestion and intraperitoneal routes. When heated to decomposition it emits toxic fumes of F- and K2O.
