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 2.0041,1800ºC 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,
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.
