Zinc oxide (ZnO), commonly known as zinc white, is a zinc oxide. Insoluble in water, soluble in acid and alkali. Zinc oxide is a commonly used chemical additives widely used in plastic, silicate products, synthetic rubber, lubricants, paints, creams, adhesives, food, batteries, flame retardants and other products of the production. Zinc oxide bandgap and large exciton binding energy, transparency, there is often Wen Faguang excellent performance in the semiconductor field of liquid crystal displays, thin-film transistors, light emitting diodes and other products are applied. In addition, the micro-particles of zinc oxide nano-materials as a starting role in related fields.
