99.9% very fine high purity magnetic powder black iron oxide magnetic powder

1. Black iron oxide is used as an iron source in ceramic applications, especially in glassware where price and its primary black color are important. Iron oxide provides the color in the glaze after firing at high temperature. High purity, low heavy metal grades are available. Our black iron powder products contain 98% or more Fe3O4. Magnetite 99% Fe3O4 (black iron oxide)

2. Black iron powder is also used as a coloring agent for a wide range of non-ceramic products.

3. Some iron oxide pigments are widely used in the field of cosmetics. They are considered non-toxic, moisture-resistant and non-bleeding. Iron oxide safe for cosmetic use is produced synthetically to avoid impurities commonly found in naturally occurring iron oxide.

4. Black iron oxide or magnetite is also used for corrosion resistance purposes. Black iron oxide is also used in anti-corrosion coatings (on many bridges and the Eiffel Tower).

5. Iron oxide is used as a contrast agent in magnetic resonance imaging to shorten proton relaxation times (T1, T2 and T2). Superparamagnetic contrast agents consist of a water-insoluble crystalline magnetic core, usually magnetite (Fe3O4). The average core diameter ranges from 4 to 10 nm. This crystalline nucleus is usually surrounded by a layer of dextrin or starch derivatives. The total size of the particles is expressed as mean hydrated particle size
