Zinc metal powder is a fine, greyish-white powder that is made up of tiny particles of pure zinc metal. It is produced by reducing zinc oxide or zinc sulfate with a reducing agent, typically carbon or hydrogen gas, at high temperatures.

Zinc metal powder has a wide range of applications, including as a raw material for the production of various zinc-based alloys and as a corrosion-resistant coating for steel and other metals. It is also used in the manufacture of batteries, electronics, and fireworks, among other products.

The properties of zinc metal powder depend on its particle size, which can range from a few microns to several millimetres in diameter. Finer particles tend to be more reactive and have a larger surface area, making them more suitable for certain applications.

Zinc metal powder is generally considered safe and non-toxic when handled properly, although it can be flammable and may pose a fire hazard in certain circumstances. It should be stored in a dry, cool place and handled with appropriate safety equipment, such as gloves and protective eyewear.
