Product Description


-11_02.jpg


1.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. Magnetite 99% Fe3O4 (Black Iron Oxide)


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


3.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.


4.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).


5.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
