Tungsten(IV) oxide(CAS: 12036-22-5)

Tungsten(IV) oxide, also known as tungsten dioxide, is a chemical compound with the formula WO2. It is a white, amphoteric oxide of tungsten. This compound is insoluble in water but soluble in acids and bases.

Tungsten(IV) oxide is widely used in various applications such as refractory materials, electrical contacts, pigments, and in the production of tungsten carbide for tools and cutting edges. It is also utilized in some electronic components and as a colorant in ceramics.

Tungsten(IV) oxide is relatively safe under normal conditions but should be handled with care. It is not toxic but can irritate the skin and eyes. Proper ventilation and the use of personal protective equipment (PPE) such as gloves and safety glasses are recommended to prevent inhalation and skin contact.

Tungsten(IV) oxide should be stored in a cool, dry place away from direct sunlight and heat sources. It should be kept in a sealed container to prevent moisture and air exposure. Avoid storing it near incompatible materials such as acids and bases to prevent chemical reactions.
