| POTASSIUM HEPTAFLUOROTANTALATE(V) Usage And Synthesis |
| 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 | Nonflammable | | Safety Profile | Poison by ingestion and
intraperitoneal routes. When heated to
decomposition it emits toxic fumes of F-
and K2O. |
