Product Name:Vanadium dioxide
English Name:Vanadium dioxide
CAS No.:12036-21-4
Aliases:Vanadium(IV) oxide, Vanadium oxide (VO2)
Molecular Formula:VO2
Physical Properties:Deep blue powder crystal. Density: 4.339 g/mL at 25°C; melting point: 1967°C. Insoluble in water, soluble in acids and alkalis; amphoteric. Dissolves in acids to form vanadyl(IV) ions (VO2+) and in alkalis to form vanadites. Slowly oxidizes in air and reacts with nitric acid to form vanadium pentoxide. Exhibits a reversible metal-insulator transition at approximately 68°C. Flammable.
Uses:Vanadium dioxide is an important smart functional material. Due to its reversible metal-insulator transition, it is widely used in thermochromic smart windows, optical switches, infrared detectors, and laser protection devices. It is also employed as a catalyst, a pigment, and an intermediate for preparing other vanadium compounds, and has been studied as a cathode material for lithium batteries.
Technical Specifications:
Purity: ≥99.9%
Molecular weight: 82.94
Density: 4.339 g/mL at 25°C
