Property of Zinc Oxide:
Zinc Oxide powder is a white or light yellow powder, non-toxic, no odor. Its density is 5.6/ cubic meters, the molecular weight is 81.4, the sublimation temperature is 1800 degrees celsius. Insoluble in water, soluble in strong acid and strong alkali.
There are three ways to make a Zinc Oxide, that is, the indirect method (France), the direct method (the United States method) and the wet chemical method. The indirect method for metal zinc ingots as raw material, the zinc melt into the evaporation in the crucible by burning hot air through air oxidation, cooling and trapping for finished products. The direct method takes the zinc oxide ore as the raw material, and the coal powder as the reducing agent, and the zinc vapor generated by the direct combustion at high temperature and the hot air contact oxidation to generate the product of Zinc Oxide, cooling and trapping. Wet chemical method using zinc as raw material, the raw material dissolved in acid, with delivery to obtain refined zinc sulfate solution, adding a precipitating agent for zinc carbonate, the roasting solution by Zinc Oxide.
