Zinc oxide is an inorganic substance with the chemical formula ZnO, which is an oxide of zinc. Insoluble in water, soluble in acid and strong alkali. Zinc oxide is a common chemical additive widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints, ointments, adhesives, food, batteries, flame retardants and other products. Zinc oxide has large energy band gap and exciton binding energy, high transparency, and excellent luminescence performance at room temperature. It is used in liquid crystal displays, thin film transistors, light emitting diodes and other products in the semiconductor field. In addition, microparticles of zinc oxide have also begun to play a role in related fields as a nanomaterial.
The applications of zinc oxide powder are numerous, and the principal ones are summarized below. Most applications exploit the reactivity of the oxide as a precursor to other zinc compounds. For material science applications, zinc oxide has high refractive index, high thermal conductivity, binding, antibacterial and UV-protection properties. Consequently, it is added into materials and products including plastics, ceramics, glass, cement,rubber, lubricants,paints, ointments, adhesive, sealants, concrete manufacturing, pigments, foods, batteries, ferrites, fire retardants, etc.
