Process

We manufacture Zinc Oxide by the French process. In this way of production, the starting material is Zinc, which is made volatile by the medium of heat. This volatile vapour is drawn into an oxidation chamber where it reacts with oxygen. Controlled conditions at the oxidation stage produce the particle size conforming to the individual grades manufactured. When cooled, the zinc oxide is collected, sampled & analyzed to ensure conformity to grade specifications. The purity, consistency & uniformity of particle size are assured through the application of Statistical Process Control & Quality Assurance.
