    Zinc oxide (ZnO) is a fine white powder. The first use of industrially manufactured zinc oxide was the production of white paints. Three different processes are used for its manufacture – two thermal processes and a wet chemical process. One thermal process starts from metallic zinc, the other from oxidic zinc residues or ores. In both processes, zinc vapour is generated and burned to zinc
