Zinc oxide (zno), commonly known as zinc white, is a zinc oxide. Insoluble in water, soluble in acid and alkali. Zinc oxide is a commonly used chemical additives widely used in plastic, silicate products, synthetic rubber, lubricants, paint, ointments, adhesives, food, batteries, flame retardants and other products of production. Zinc oxide bandgap and large exciton binding energy, high transparency, excellent performance often wen faguang, the field of liquid crystal display in the semiconductor, thin film transistors, light emitting diodes and other products in both applications. In addition, micro particles of zinc oxide nanomaterials have begun as a field in related work.
