PRODUCTS CENTER
White crystal or powder, belonging to the hexagonal crystal system. Odorless, non-toxic, no sand, fine quality. Density 5.606g/cm3, refractive index 2.0041,1800 C sublimation. The tinting strength is 2 times that of basic lead carbonate, and the hiding power is half of that of titanium dioxide and zinc sulfide. Insoluble in water and ethanol, soluble in acid, sodium hydroxide, ammonium chloride, is an amphoteric oxide. It is yellow when heated at high temperature and returns to white after cooling. In the humid air can absorb carbon dioxide and moisture gradually become basic zinc carbonate. It can also be reduced to zinc metal by carbon or carbon monoxide. There is excess zinc in the zinc oxide lattice, the initial ionization energy of zinc is relatively low, easy to lose electrons, and zinc oxide electron mobility is much larger than the hole mobility, can be regarded as n-type semiconductor.
