產品描述

Iron(II,III) oxide is the chemical compound with formula Fe3O4. It is one of a number of iron oxides. It is found in nature as the mineral magnetite. It contains both Fe2+ and Fe3+ ions and is sometimes formulated as FeO.Fe2O3. It is encountered in the laboratory as a black powder. It exhibits permanent magnetism and is ferrimagnetic, but is sometimes incorrectly described as ferromagnetic. Its most extensive use is as a black pigment which is synthesised rather than being
extracted from the naturally occurring mineral as the particle size and shape can be varied by the method of production.
