Zinc oxide (ZnO), commonly known as the XinBai, is a kind of zinc oxide. Soluble in water, soluble in acid and alkali. Zinc oxide is a common chemical additive, widely used in plastic, Portland products, synthetic rubber, lubricating oil, paint coating, ointment, adhesives, food, battery, flame retardant agent in the manufacture of products. The band gap and zinc oxide excitons bound to larger, transparency, have excellent room temperature luminous property, in semiconductor areas of liquid crystal displays, thin film transistor, light emitting diode and other products are in the application. In addition, micro particles of zinc oxide as a kind of nanometer materials also began in the related field work.
