Hazard Information | Back Directory | [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. | [Hazard]
Toxic by inhalation. | [Flammability and Explosibility]
Nonflammable |
