Technical Document

Brief Overview

Zinc oxide, with the chemical formula ZnO, is an inorganic compound that presents itself as a white, water-insoluble powder. It plays a foundational role in numerous applications, including pharmaceuticals, cosmetics, antiseptics, soaps, ointments, animal feed, zinc-derived chemicals, matches, paints, pigments, ceramics, adhesives, plastics, and rubber tire additives. Despite its natural occurrence in the earth's crust as zincite, the commercially utilized zinc oxide is primarily synthetic.

Manufacturing Process

Various grades of zinc oxide can be produced using electrolytic zinc from approved suppliers. In the French Process for zinc oxide production, zinc undergoes controlled melting, vaporization, and oxidation to attain particle sizes specific to different grades. Following the cooling process, the zinc oxide is collected, sampled, and analyzed to ensure adherence to grade specifications. The implementation of statistical process control and quality assurance techniques guarantees the purity, consistency, and uniformity of particle size, establishing a connection between the quality assurance laboratory, production, and sales departments through an information system.
