Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of ...

Magnetite forming in iron pipes. Magnetite, with chemical formula: Fe3O4, is an iron ore found in igneous, metamorphic rocks. It belongs in the same group of iron ore as the hematite or the maghemite. Magnetite is a chemical compound of iron and oxygen and therefore an oxide. Magnetite is physically rather stable, as it is an octahedral crystal.
09-11-2008· If you take your powder, which I have no doubt is at least 80 or 90% magnetite, and make a sludge with some oil or other solvent, it'll be magnetic, and act a little bit like a ferrofluid, but when all is said and done it won't be a liquid, or a colloid. At best it will be a temporary suspension. None the less fun for it, though, I imagine.

Aluminum powder performs best on glass, plastic, and rubber. Bi-chromatic powder, on the other hand, is typically a combination of black and aluminum powder, although some manufacturers combine the black with a variety of other colors. The idea behind the creation of the bi-chromatic powder was to assist the examiner with multi-colored surfaces.
