Fe3O4 has found interesting and important applications in different science

As a ferromagnetic powder and conductive material, Fe3O4 has found interesting and important applications in different science, technology, and industry sectors. Fe3O4 magnetic powder has a very common application as black pigment. The time-dependent magnetism property of Fe3O4 is an advantage for applications at different temperatures for particular purposes. The unique electronic structure of Fe3O4 originates from the combination of ferric and ferrous ions, making it a superconductor while being a super magnetic material. Among other industries, Iron oxide Fe3O4 nanoparticles are used as magnetic data storage, biosensors, drug delivery, ferrofluids, magnetic coatings, EM-waves absorbing coatings, and wastewater purification. Fe3O4 was synthesized by the coprecipitation method using FeCl3. 6H2O and (NH4)2Fe(SO4)2. 6H2O precursors dissolved in distilled water in a mol ratio of Fe3+: Fe2+ = 2:1. NaOH solution was added slowly into the iron solution with continuous stirring for 60 minutes in an Argon gas atmosphere. Magnetite (Fe3O4), which has an inverse spinel structure, has a high conductivity as a result of electrons jumping between the octahedrally coordinated Fe2+ ions and the Fe3+ ions (octahedrally and tetrahedrally coordinated). For this reason, magnetite has been the subject of several studies by STM. Magnetite (or Fe3O4) is an elaborate rust – a regular oxygen and iron atoms lattice. But this material plays an important role as a catalyst in electronic devices and medical applications. A synthesis of the Fe3O4 particle as a ferrofluid filler with surfactant oleic acid dispersed in olive oil has successfully been performed. The magnetic nanoparticle has a particle size of 8.8 nm sized particles. Ferrimagnetic Fe3O4 on heating to 850 K becomes paramagnetic. This is due to the greater alignment of domains (spins) in one direction on heating.
