Triiron tetraoxide (Cat No.: M047566), also known as magnetite, is a mixed-valence iron oxide containing both Fe²⁺ and Fe³⁺ ions. It occurs naturally as a black, magnetic mineral and is widely used in magnetic materials, data storage, and biomedical applications such as MRI contrast agents and targeted drug delivery. Due to its high electrical conductivity and magnetic properties, it is also employed in catalysis, water treatment, and electronic components. Fe₃O₄ exhibits a spinel crystal structure and excellent chemical and thermal stability.
