What Is VANADIUM(IV) OXIDE Cas 12036-21-4

Vanadium dioxide (VO2) is a strongly correlated electron system binary oxide. Due to the strong interactions between its internal electrons, orbitals, lattice, and spin, changes in local electrons and crystal structure caused by small external stimuli can induce VO2 to undergo reversible metal transformation. The crystal structure, resistance, infrared transmittance, refractive index and magnetic susceptibility of VO2 change dramatically. It is precisely because of the phase transition temperature near room temperature and the sudden changes in physical and chemical properties before and after the phase transition that VO2 has a very broad application prospect in electronics, military, daily life, and other fields.

Vanadium(IV) oxide is used in chemical sensors, energy-conserving coatings, transparent conductors and switching materials. It acts as a stationary optical shutter, optical modulators, cameras and data storage. As infrared modulators, it is used for the missile guidance systems. Thin films made up of vanadium dioxide find applications in electro-optical switches, micro-optical switch, passive smart radiators and sunshields for spacecraft.
