Tantalum pentoxide Usage And Synthesis
  • Chemical Propertieswhite to white-beige powder
  • UsesTantalum pentoxide is used in making high refractive index optical glass; as a dielectric film on tantalum for its use as a capacitor component and rectifier; and for preparing tantalum metal, its carbide, and many other tantalum compounds.
  • UsesTantalum oxide is used to make optical glass for lenses and in electronic circuits.
  • UsesTantalum pentoxide (Ta2O5) is used to make special optical glass, for lasers, and in electronic circuits.
  • PreparationTantalum pentoxide is obtained as an intermediate in extracting tantalum from the columbite-tantalite series of minerals. Also, the oxide can be made by heating Ta metal in oxygen or air at elevated temperatures.
  • HazardTLV: 5 mg/m3.
  • Safety ProfileMildly toxic by ingestion. Incompatible with ClF3, BrF3, Li. See also TANTALUM.
