Zinc Oxide( ZnO) Nanopowder General Description
A fine powder ranging in color from white to light yellow, this material is composed of 99.8% or purer zinc oxide particles ranging from 10nm to 30nm in diameter.
This nanomaterial is one with a broad range of applications across multiple domains, acting as a raw material for products as disparate as cigarette filters and
cosmetics. The material is also known for corrosion-resistance, antibacterial and antifungal properties, and its viability as an effective UV filter.
Zinc Oxide( ZnO ) Nanopowder Applications
• Filters. There are several filtration applications for zinc oxide, due to its general anti-microbial properties and strength. Most commonly, the material is seen in cigarette filters.
• Rubber. Various rubbers utilize zinc oxide nanoparticles in the manufacturing process, primarily as a raw material but sometimes as a coating or catalyst.
• Concrete. As with rubber, zinc oxide nanoparticles are used primarily as a raw material in the manufacture of certain concretes.
• Ceramics. Like other nanomaterials with antimicrobial properties, zinc oxide nanopowders are of value in the production of ceramics, especially those for use in sterile environments.
• Cosmetics. Many creams, ointments, moisturizers, and beauty products utilize zinc oxide for its antimicrobial, optical, and health properties.
• Coatings. As with many nanomaterials, zinc oxide nanoparticles are used in various specialty coatings to impart the unique properties of the material at a relatively low cost—in this case, UV filtration and antimicrobial benefits. Many paints use zinc oxide particles specifically as a coating agent.
• Food. Zinc oxide is fairly common as a food additive in fortified processed meals such as breakfast cereal. This is done to supplement zinc, which can’t be digested in its pure form.
• Skin treatments. Calamine lotion is made using zinc oxide powders, as are any number of other ointments, creams, washes, rinses, and other treatments used to control or prevent certain skin diseases.
