Black
Iron Oxide (Magnetite)
| Black iron oxide is used as a source
of Fe in ceramic applications, particularly in glazing where price and
its black raw color are important. Iron oxide provide the color in glaze
after being fired at high temperatures. High purity, low heavy metal
content grades are available. Our black iron powder products have 98% or
more Fe3O4. |
 |
Black iron powder is also used as
a colorant for a wide range of non-ceramic products.
Some iron oxide pigments are widely used in the cosmetic field. They are
considered to be nontoxic, moisture resistant, and nonbleeding. Iron oxides
graded safe for cosmetic use are produced synthetically in order to avoid the
inclusion of impurities normally found in naturally occurring iron oxides.
Black iron oxide or magnetite is also used for corrosion resistance purposes.
Black iron oxide is also used in anti-corrosion paints (used in many bridges,
and Eiffel tower).
Iron oxides are used as contrast agent in Magnetic Resonance Imaging, to shorten
proton relaxation times, (T1, T2 and T2). The super paramagnetic contrast agents
are composed of a water insoluble crystalline magnetic core, usually magnetite
(Fe3O4). The mean core diameter ranges from 4 to 10 nm. This crystalline core is
often surrounded by a layer of dextrin or starch derivatives. The total size of
the particle is expressed as the mean hydrated particle diameter.
