Iron Oxide Black Food grade - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | Iron oxide Black is a black powder, which is an adduct of iron oxide and ferrous oxide. General content of ferrous oxide, hiding power is very high. Color strength is very large, but less than carbon black. The effect on sunlight and the atmosphere is stable. Resistant to all alkali, but soluble in acid, a strong magnetic. Calcined in the presence of sufficient air, easily oxidized to red iron oxide. |
| Application | is mainly used for making primer and topcoat, and also used as rust inhibitor in construction industry. High purity is an excellent magnetic material for coating audio tapes. As an important iron-based pigment, iron oxide black is used in watercolors and inks, and the main raw material of magnetic carbon powder for copying machines is needle-shaped iron oxide black. In addition, iron oxide black because of its non-toxic, pollution-free characteristics, can also be used for the production of advanced cosmetics. |
| Use | for pigments and polishing agents, for coatings, plastic and building surface coloring |
