Zinc oxide is also a semiconductor material. Zinc oxide bandgap and exciton binding energy is relatively large, transparent, with excellent luminescent properties at room temperature, in the liquid crystal display, thermal insulation glass, thin-film transistors, light emitting diodes and other products are applied.

Zinc oxide powder, zinc oxide [3] (English: Zinc Oxide), commonly known as zinc white, the chemical formula ZnO, is a kind of zinc oxide. Difficult to dissolve in water, soluble in acid and alkali. Zinc oxide is a commonly used chemical additives, is widely used in plastics, ceramics, glass, cement products, synthetic rubber, lubricants, paints, creams, adhesives, sealants, paints, food, batteries, flame retardants and other products the preparation. Nature of zinc oxide zinc present in the red, but the use of industrial production of zinc oxide is usually burning or roasting of sphalerite zinc obtained.
