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 kind of common chemical additives, widely used in plastic, Portland products, synthetic rubber, lubricating oil, paint coating, ointment, adhesives, food, battery, flame retardant agent and the manufacture of products. Zinc oxide band gap and excitons bound to larger, high transparency, have excellent performance in normal temperature, light in the semiconductor industry LCD monitor, thin film transistor, led (light-emitting diode) and other products which is used. In addition, micro particles of zinc oxide as a kind of nanometer materials also began in the related field work.
