New product Reduced iron powder use for Precious metal reduction

Reduced iron powder, gray or black powder, also known as "double-suction", can absorb moisture and oxygen in the air, and is often used for food preservation.

 

The reduced iron powder is generally produced by the reduction of ferroferric oxide in a hydrogen stream or a carbon monoxide gas stream under high heat conditions, and the main component is a structurally loose elemental iron. Since the reduced iron powder itself is powdery, and its microstructure is very loose, its surface area is extremely large. It is often used as a high quality reducing agent in chemical production and laboratory operations.
