Zinc oxide (ZnO), commonly known as 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 plastics, Portland products, synthetic rubber, lubricating oil, paint coating, ointment, adhesives, food, batteries, flame retardants etc products in making. Zno band gap and excitons bound to larger, transparency, have excellent luminous property, normal temperature in the semiconductor industry of LCD, thin-film transistors, light emitting diode products in both applications. In addition, micro particles of zinc oxide as a kind of nanometer materials also began in the related field play an important role.
