This is a synthetic form of black iron oxide that runs <1 micron in size compared the natural black iron oxide that we sell that runs 30-45 microns in size. It is ideal for pigments and other uses where a very small particle size is desired. Also, it is a truer black since it has fewer impurities (clay, silica, etc.).

Chemical structure - Fe₃O₄

Shipped in 2 - 5 lb resealable foil bags.

Iron oxide has many uses including pigments, ceramics, and thermite welding, along with a wide range of other uses.
