Zinc oxide (Zinc oxide), with the chemical formula ZnO, is an inorganic compound with a molecular weight of 81.39 g/mol and is a white solid. Zinc oxide is insoluble in water and ethanol, but soluble in acids and strong bases, and has a high melting point and boiling point. It is a commonly used chemical additive and is widely used in plastics, silicate products, synthetic rubber, lubricants, paints and coatings, ointments, adhesives, food, batteries, flame retardants and other products.
Physical and chemical properties
Zinc oxide has a large band gap and exciton binding energy, high transparency, and excellent room-temperature luminescence performance. Its band gap at room temperature is about 3.3 eV, and its exciton binding energy is as high as 60 meV, which makes it important in the semiconductor field, such as liquid crystal displays, thin film transistors, light-emitting diodes and other products. In addition, zinc oxide is also an important sunscreen that can absorb ultraviolet radiation.
Application areas
Chemical industry: used as an additive in plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, etc.
Electronic Industry: Used to make semiconductor materials, such as thin film transistors, light-emitting diodes, etc.
Medical Field: Used to make ointments and sunscreens.
Feed Additive: Used in mixed feed to provide zinc and promote animal health.
Manufacturing Methods
Zinc oxide can be prepared by burning zinc or roasting sphalerite (zinc sulfide). In nature, zinc oxide is the main component of the mineral zincite.
