Iron oxide (Fe3O4), commonly known as magnetite, is a black, magnetic mineral and one of the primary iron ores. It is characterized by its mixed-valence state, containing both Fe(II) and Fe(III) ions, which contributes to its unique magnetic properties. Magnetite is insoluble in water and exhibits a high melting point, making it stable under various environmental conditions. It has a cubic crystal structure and is often found in igneous and metamorphic rocks, as well as in sedimentary deposits. Due to its magnetic properties, Fe3O4 is widely used in various applications, including magnetic recording media, catalysts, and as a pigment in paints and coatings. Additionally, it plays a significant role in the production of iron and steel. The substance is also of interest in biomedical applications, particularly in drug delivery and magnetic resonance imaging (MRI) due to its biocompatibility and ability to be manipulated by external magnetic fields. Safety data indicates that while it is generally considered low in toxicity, appropriate handling precautions should be observed to minimize inhalation or prolonged exposure.
