commonly known as zinc white, is an outcome of zinc by oxidation. Insoluble in water, soluble in acid and alkali. Zinc oxide as chemical additives is usually and widely used in plastic, silicate products, synthetic rubber, lubricants, paint, medicines, adhesives, food, batteries, flame retardants and other relevant fields. Zinc oxide has large bandgap and exciton binding energy, high transparency and excellent performance of in normal temp., so it also make wide applications in the field of liquid crystal display in the semiconductor, thin film transistors and light diodes . In addition, micro particles of zinc oxide is a kind of nano-materials to work on some relevant products
