White powder of Zinc oxide (ZnO), commonly known as zinc white, is an oxide of zinc. A semiconductor material formed by the combination ofⅡB element Zn and VI element O. The molecular formula is ZnO. The band gap at room temperature is 3.2eV, which is a direct transition type band structure. Hardly soluble in water, soluble in acid and strong alkali. White powder of Zinc oxide is a commonly used chemical additive, which is widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints, ointments, adhesives, food, batteries, flame retardants and other products.
