POTASSIUM HEPTAFLUOROTANTALATE(V) Chemical Properties,Uses,Production
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.
Chemical Properties
White, silky needles. Slightly soluble in cold water; quite soluble in hot water.
Uses
Intermediate in preparation of pure tantalum.
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.
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.
