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

by reduction of iron in magnetite under high heat in the flow of hydrogen or carbon monoxide gas reduction generation, mainly composed of iron loose structure. Due to the reduction of iron powder itself has been powder, coupled with its microstructure is very loose, so its surface active. It is often used as a high quality reducing agent in chemical production and laboratory work.

Application:
