Zinc Oxide Powder

Listing ID #3700491

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 oxide. In the wet process, zinc is leached from zinc containing raw materials and then precipitated as zinc hydroxide-carbonate. The precipitate is calcinated to ZnO.
