CAS No.: 12036-21-4 Formula: O2V Molecular Weight: 82.94030

Description

Vanadium(IV) dioxide is an inorganic compound with the formula VO2. It is a dark blue solid. Vanadium(IV) dioxide is amphoteric, dissolving in non-oxidising acids to give the blue vanadyl ion, [VO]2+ and in alkali to give the brown [V4O9]2− ion, or at high pH [VO4]4−. VO2 has a phase transition very close to room temperature(~66°C). Electrical resistivity, opacity, etc, can change up several orders. Due to these properties, it has been widely used in surface coating, sensors, and imaging. Potential applications include use in memory devices.
