What is Vanadium trioxide?

Vanadium trioxide (CAS 1314-34-7), also known as vanadium(III) oxide or V2O3, is an inorganic vanadium compound used primarily as a catalyst precursor and functional material in high-temperature industrial processes.

Where is Vanadium trioxide used?

  • Vanadium chemical production and specialty electronic components: key intermediate
  • Metallurgy: feedstock for ferrovanadium and other vanadium alloys
  • Chemical synthesis: catalyst precursor whose controlled reduction to active vanadium species drives selective oxidation reactions
  • Electronics: V2O3 thin films and powders for thermistors and switching devices, exploiting its metal-insulator transition
  • It also serves as a starting material in the preparation of higher vanadium oxides, including vanadium pentoxide.

Commercial specifications

  • Fine black or dark gray powder in technical and high-purity grades
  • Purity levels range from 98% to 99.9%+
  • High-purity grades available for electronics and research
  • Packaging in multi-kilogram quantities up to bulk industrial supply, depending on grade and application requirements
