Introduction:

Zinc doxide appearance is white powder, high activity, nanometer scale. It has excellent antibacterial and UV shielding properties and high catalytic activity. Nano inorganic material, non-toxic, non-irritating, durable and stable performance.Zinc oxide has large band gap and exciton binding energy, high transparency, excellent luminescence performance at room temperature, and has been used in liquid crystal display, thin film transistor, light emitting diode and other products in the field of semiconductor. In addition, microgranular zinc oxide as a kind of nanomaterial also began to play a role in related fields

Zinc Oxide (ZnO) is a functional fine inorganic product. ZnO nanopowder shows many special properties, such as non-migratory, fluorescent, piezoelectric, absorption and scattering UV capability. Zinc oxide nano powder is with wonderful performance in optical, electrical, magnetic, and other sensitive areas .It widely used in plastics, silicate products, synthetic rubber, lubricating oil, paint coatings, ointment, adhesives, food, batteries, flame retardant and other products in the production.
