Black Iron Oxides Brenntag

Black Iron Oxides Brenntag

Huntsman Synthetic Black Iron Oxides are precipitated magnetite (Fe3O4). Typically, the ferrous content is approximately 24% expressed as FeO. They yield deep black masstone color and rich bluish black tints, have excellent hiding power, and are low in heavy metals content. Wetting, dispersion and suspension properties are excellent.

Magnetite Applications and Uses African Pegmatite

Magnetite Applications and Uses African Pegmatite

Magnetite is the primary source material for this. Ground magnetite is partially reduced, relieving it of some of its oxygen, leaving a catalyst bearing a magnetite core with an outer shell of ferrous oxide (FeO, w rstite). The advantage of this catalyst comes in its porosity, and thus it is a highly active, high surface area material.
