CAS 1317-61-9: Iron oxide (Fe3O4)

Description: Iron oxide (Fe3O4), commonly known as magnetite, is a black, crystalline solid that exhibits both ferromagnetic and ferrimagnetic properties. It is an inorganic compound composed of iron in both the +2 and +3 oxidation states, which contributes to its unique magnetic characteristics. Magnetite is insoluble in water and most organic solvents, but it can dissolve in strong acids. It has a high melting point and is stable under a wide range of temperatures. This compound is commonly found in nature as a mineral and is often used in various applications, including as a pigment, in magnetic materials, and in the production of iron and steel. Additionally, Fe3O4 is utilized in environmental remediation processes to remove heavy metals and contaminants from water. Its magnetic properties make it valuable in biomedical applications, such as targeted drug delivery and magnetic resonance imaging (MRI) contrast agents. Overall, iron oxide (Fe3O4) is a versatile material with significant industrial and scientific importance.
