What is zinc dust?
Zinc dust is a fine (bluish) gray powder of zinc metal that is produced by distilling zinc in closed, horizontal furnaces. The vapor emitted from the zinc is then condensed as dust. Zinc dust is primarily used in paints and coatings to inhibit corrosion. It offers working support as protective pigment in industrial coatings. It is used as catalyst in many chemical reactions. Furthermore, zinc dust is employed as reducing agent and works as precipitant for metals such as copper, gold, silver, and cadmium.
