Zinc oxide Chemical Properties,Usage,Production

Chemical Properties
white powder
General Description
Crude zinc oxide is a yellow-gray granular solid with no odor. Zinc oxide has a specific gravity of 4.4. Zinc oxide is insoluble in water. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Prolonged inhalation of the dust may result in metal fume fever with symptoms of chills, fever, muscular pain, nausea and vomiting.
Air & Water Reactions
Slowly decomposed(hydrolyzed) in water. Insoluble in water.
Reactivity Profile
ZINC OXIDE is insoluble in water. What little solubility Zinc oxide has yields aqueous solutions that are neutral in pH. Intimate mixtures of zinc oxide and chlorinated rubber with or without hydrocarbons or chlorinated solvent react violently, even explosively upon heating [Chem. Trade J., 1962, 151, 672]. Slow addition of zinc oxide to cover the surface of linseed oil varnish caused generation of heat and ignition, [Chem. Trade J., 1933, 92, 278].
Fire Hazard
Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.
