Description of Zinc oxide
Zinc oxide is white crystal or powder, belonging to the hexagonal crystal system. Odorless, non-toxic, sand free, fine quality. Density 5.606g/cm3, refractive index 2.0041,1800℃ sublimation. The coloring power is twice that of basic lead carbonate, and the covering power is half that of carbon dioxide and zinc sulfide. Insoluble in water and ethanol, soluble in acid, sodium hydroxide, ammonium chloride, amphoteric oxide. Yellow when heated at high temperature and white when cooled. In humid air, it absorbs carbon dioxide and water and gradually becomes basic zinc carbonate. Can also be reduced to zinc metal by carbon or carbon monoxide. Zinc oxide lattice has excess zinc, the first ionization energy of zinc is relatively low, easy to lose electrons, and zinc oxide electron mobility is much larger than hole mobility, can be regarded as N-type semiconductor.
Application of product
Zinc oxide, also known as zinc white, is a pure white powder composed of small amorphous or needle-like particles. As basic chemical raw materials, it has a wide range of applications, such as rubber, electronics, coatings and other industries. Function and efficacy Zinc oxide can be used as a white pigment for printing and dyeing, paper making, matches. In the rubber industry used as natural rubber, synthetic rubber and latex vulcanized active agent, reinforcing agent and colorant. Also used in pigment zinc chrome yellow, zinc acetate, zinc carbonate, zinc chloride and other manufacturing. In addition, it is also used for electronic laser materials, phosphors, etc.
Function of product
Zinc Oxide (ZnO) is a functional fine inorganic product. ZnO nanopowder shows many special properties, such as non-migratory, fluorescent, piezoelectric, absorption and scattering UV capability. Zinc oxide nanopowder is with wonderful performance in optical, electrical, magnetic, and other sensitive areas.
