About Zinc Dust:  Properties & Uses
A pure and fine gray powder of zinc metal, It is made by distilling primary or secondary zinc in closed, horizontal furnaces. The vapor emitted from the zinc is then directed into large condensers and condensed as dust.
 
It is Grey in color, shape is spherical, controlled by the rate of distillation and condensation. It is categorized as a hazardous material and extremely sensitive to moisture
it Also known as Fine Zinc Powder, it is finely divided zinc metal, at least 97% pure. It is also termed as a fine gray powder of zinc metal, made by distilling primary or secondary zinc in closed, horizontal furnaces. The vapor emitted from the zinc is then directed into large condensers and condensed as dust.

One of the most widely demanded metal powder in the market, it is sought by industries engaged in the business of chemical formulation, brake pads, paints, and lubricants and sintering. It also serves as protective pigment in industrial coatings or as reducing agent and catalyst in various chemical reactions.
it is categorized as a hazardous material & is extremely sensitive to moisture. Therefore it is highly recommended to store in a cool, dry and well ventilated area, removed from water or moisture, oxidizing agents, acids, alkalies, heat or ignition sources and foodstuffs. Also ensure containers are adequately labeled, protected from physical damage and sealed when not in use. Large storage areas should have appropriate ventilation systems.

While handling, ensure that you avoid inhalation as well as contact with eye or skin. Also observe good personal hygiene, including washing hands before eating.
