What is zinc oxide
Zinc oxide (ZnO) is a white powder that manufacturers now use for a variety of medicinal and industrial purposes. Although it is available in its natural state, the processing of zinc oxide typically must occur for manufacturing applications. An indirect process for producing zinc oxide consists of melting metallic zinc to produce a vapor that reacts with atmospheric oxygen to form ZnO. The direct method entails heating zinc ore with carbon to create a zinc vapor followed by oxidization. Employing a wet chemical processing technique is another option.

Zinc Oxide Properties and Characteristics
Zinc oxide has a good heat capacity and thermal conductivity, as well as high temperature stability. It is possible to synthesize ZnO into various forms and structures such as nanowires, tetrapods, nanobelts, and nanorods. The material is non-toxic, although it is hazardous to inhale zinc oxide fumes produced during oxidization at high temperatures. The FDA classifies the compound as generally recognized as safe (GRAS) for use as a food additive.
Zinc Oxide Uses and Applications
- Ceramics: zinc oxide enhances the elasticity of glazes by helping prevent issues such as
shivering and crazing
- Concrete: adding zinc oxide assists in the processing of concrete and increases its
Food additive: zinc oxide can serve as a source of dietary zinc that helps to promote
immune system health; breakfast cereals and other prepackaged foods often contain
small amounts of ZnO
- Manufacturing: in an industrial setting, ZnO can help prevent corrosion in finished
products made of metal
- Rubber: ZnO combines with stearic acid for the vulcanization of rubber
