What mineral group is Fe3O4

Magnetite, also called lodestone or magnetic iron ore, is an iron oxide mineral (FeFe2O4 or Fe3O4) that is the chief member of one of the spinel (q.v.) group series. When heated with hydrogen, magnetic oxide (Fe3O4) is reduced to iron, and water is also produced. Write a balanced equation for the reaction. Fe3O4 occurs as a mineral named Iron (II, III) oxide. It is stone-iron-like, brownish to grey or black. It is demonstrated that the Fe3O4/PANI suspension has a good electrical conductivity that is up to 2.135 μS/cm at the optimal ratio of reactants. The Fe3O4 nanoparticles are well dispersed in the PANI network with a particle size of about 10 nm. Popular answers (1) Magnetite Fe3O4 is a famous material with a metal-insulator transition at T = 120 K. The transition is also called the Verwey transition. So at room temperature, Fe3O4 is a conductor, whereas it is an insulator at a temperature below 120 K. The oxidized magnetite (Fe3O4), which resulted in the formation of hematite (Fe2O3), was then reduced by using a continuous stream of CO (5% and 10%) with an N2 balance. The oxygen weight gain determined the rate of oxidation. Analysis of the data indicated that the oxidation behavior followed a two-stage process. Therefore, Fe3O4 is a ferrimagnetic material with high saturation magnetization (MS) and low coercivity (HC) due to the antiferromagnetically coupled Fe3+ cations in tetrahedral and octahedral sites of its crystal structure.
