Ferric oxide is also called iron oxide (II, III), Fe3O4. Black Fe3O4 is a mixed valence oxide of iron with a melting point of 1597 ℃ and a density of 5.18g/cm3. Insoluble in water, soluble in acid solution. It appears in nature in the form of magnetite, with strong submagnetite and high conductivity at room temperature.
Ferromagnetic and ferromagnetic materials undergo a second-order phase transition to paramagnetic materials above the Curie temperature. The Curie temperature of Fe3O4 is 585 ℃.
Nano Fe3O4 (Fe3O4) powder is magnetic and can move directionally in an external magnetic field. Its particle size is superparamagnetic within a certain range and can generate heat under the action of an external alternating electromagnetic field. Its chemical properties are stable, so it has a wide range of uses.
Iron oxide Fe3O4 overview
Iron oxide(II,III)(Fe3O4) is a highly insoluble and thermally stable iron source suitable for glass,optical and ceramic applications.Oxide does not conduct electricity.However,certain oxides of perovskite structure have conductivity in the cathodes of solid oxide fuel cells and oxygen generation systems.They are compounds containing at least one oxygen anion and one metal cation.They are generally insoluble in aqueous solutions(water)and are very stable,making them useful for ceramic structures,as easy as producing clay bowls for advanced electronic devices,and for lightweight structural components in aerospace and electrochemical applications.For example,fuel.They exhibit ionic conductivity.Metal oxides are alkaline high-purity (99.999%) iron oxide (FeO) anhydrides,so they can undergo redox reactions with acids and strong reducing agents.Iron oxide can also be made into particles,blocks,powders,sputtering targets,tablets and nano powders.In most cases,iron oxide is usually available immediately.High purity,submicron and nano powder forms can be considered. Provide other technical,research and safety (MSDS) information.To Fe3O4 is formed by Schikorr reaction.This reaction converts iron (II) hydroxide (Fe(OH)2)into iron (II,III) oxide (Fe3O4).Under anaerobic conditions,ferrous hydroxide (Fe(OH)2) is oxidized in water to form magnetite and molecular hydrogen.Skicor's reaction explained the process.
3Fe（OH）2 → Fe3O4 + H2 + 2H2O
Hydroxide ferrous magnetite hydrogen water.
Application of iron oxide Fe3O4
Iron oxide Fe3O4 powder,usually called iron oxide black,magnetite and black iron oxide, can be used in many different fields,for example:iron oxide (II,III) is used as a black pigment,also called Martian black.
Used as a catalyst in the Haber process.
Used in water gas shift reaction.
In contrast,Fe3O4 nanoparticles are used for MRI scans.
Iron oxide Fe3O4 powder can prevent steel from rusting.
Iron oxide Fe3O4 powder is a component in aluminate,used for cutting steel.
Iron oxide Fe3O4 powder is ferromagnetic.If the radius of the formed particles is at the nanometer level,they are called ferromagnetic particles.
1.Iron oxide Fe3O4 powder can produce magnetic recording materials,high gradient magnetic separators,microwave absorbing materials,and special coatings.
2.Iron oxide Fe3O4 powder is widely used as a carrier of various pharmaceutical ingredients to form a magnetic targeted drug delivery system;for the separation of magnetic immune cells,nuclear magnetic resonance imaging and other aspects.
3.Used for precision instruments,gas seals,vacuum seals,etc.
