Description

Zinc Oxide, also known as Oxozinc, Zinc White, Zincoid, Amalox, Oxydatum, Zinci Oxicum, Ketozinc, and Nogenol, has the chemical formula ZnO. It appears as white hygroscopic powder or granules with no odor and a bitter taste. It is insoluble in Water and soluble in dilute Acetic Acid at ambient conditions. On a commercial scale, it is usually produced by two methods named Direct or American and Indirect or French method. A USP/NF Grade chemical is the one that conforms to the criteria of the United States Pharmacopeia (USP) and the National Formulary (NF). A substance that has received the USP/NF Grade certification can be used in food, drug, or medical applications. In the United States of America (USA), Lab Alley is selling its high-quality Zinc Oxide, USP/NF Grade online at laballey.com.

Zinc oxide is an inorganic compound with the formula ZnO. ZnO is a white powder that is insoluble in water, and it is widely used as an additive in numerous materials and products including rubbers, plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, and first-aid tapes. Although it occurs naturally as the mineral zincite, most zinc oxide is produced synthetically. ZnO is a wide-bandgap semiconductor of the II-VI semiconductor group. The native doping of the semiconductor due to oxygen vacancies or zinc interstitials is n-type. This semiconductor has several favorable properties, including good transparency, high electron mobility, wide bandgap, and strong room-temperature luminescence. Those properties are valuable in emerging applications for: transparent electrodes in liquid crystal displays, energy-saving or heat-protecting windows, and electronics as thin-film transistors and light-emitting diodes.
