POTASSIUM HEPTAFLUOROTANTALATE(V) Usage And Synthesis
  • Chemical PropertiesWhite, silky needles. Slightly soluble in cold water; quite soluble in hot water.
  • Chemical PropertiesPotassium 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.
  • UsesIntermediate in preparation of pure tantalum.
  • HazardToxic by inhalation.
  • Safety ProfilePoison by ingestion and intraperitoneal routes. When heated to decomposition it emits toxic fumes of F- and K2O.
