Fe3O4 Chemical Name: Iron(II, III) Oxide. Fe3O4, commonly known as magnetite, is a mixed iron oxide with the chemical formula Fe³O₄. Its systematic name is iron(II, III) oxide, reflecting the presence of both Fe²⁺ (ferrous) and Fe³⁺ (ferric) ions in a 1:2 ratio. This unique combination gives magnetite distinct magnetic, electrical, and chemical properties. It is one of the most stable iron oxides and occurs naturally as a mineral in igneous and metamorphic rocks. Magnetite is black or brownish-black with a metallic luster and is known for its strong magnetism, making it the most magnetic naturally occurring mineral on Earth. Its magnetic behavior arises from the alignment of electron spins in its crystal structure, a cubic inverse spinel arrangement. In this structure, oxygen ions form a close-packed lattice, with Fe²⁺ ions occupying octahedral sites and Fe³⁺ ions split between tetrahedral and octahedral sites. This configuration enables efficient electron transfer between iron ions, contributing to its conductivity. Fe3O4 is insoluble in water and alkaline solutions but reacts with acids. It plays a vital role in industrial applications, including as a catalyst in ammonia production, a pigment in coatings, and a component in magnetic storage media. Nanoparticles of Fe3O4 are used in biomedical fields for drug delivery, MRI contrast agents, and hyperthermia cancer treatment. Environmentally, magnetite forms in soils and sediments through microbial activity, influencing heavy metal sequestration. It also serves as an iron ore in steel manufacturing. Despite its stability, magnetite can oxidize to hematite (Fe2O3) under high temperatures or prolonged exposure to oxygen. Its versatility across technology, biology, and industry underscores its significance as a multifunctional material.
