12227-89-3
Product name: Iron Oxide Black
English alias: Ferrosoferric oxide; Magnetite; Black iron oxide.
CAS: 12227-89-3
Molecular formula: Fe3O4
Appearance: Black fine powder
Package: 25kg/bag
Iron Oxide Black is a naturally occurring magnetic iron oxide with the chemical composition Fe₃O₄, also known as magnetite. This inorganic pigment exhibits excellent tinting strength, weather resistance, and chemical stability. As one of the most important black pigments, it offers outstanding opacity, UV resistance, and thermal stability. Its unique magnetic properties make it valuable for specialized applications beyond traditional coloring uses. The synthetic form provides consistent quality and purity, making it suitable for demanding applications in coatings, construction, and electronic materials.

Can be extracted from the naturally occurring mineral, magnetite, which is then ground and processed.
Produced synthetically to control its quality and properties for specific applications. Common methods include a dry process (e.g., reacting hot iron with steam) or a wet process (e.g., oxidizing an iron(II) salt solution).
Iron Oxide Black is generally considered non-toxic and non-irritating. However, inhalation of dust should be avoided. Use appropriate personal protective equipment including dust mask when handling powder form. The pigment is stable under normal conditions and does not present significant health hazards when used properly.
keep the product dry
relative humidity < 50%
