The properties and applications of Iron Oxide Fe3O4

What Is Iron Oxide Fe3O4 ? Iron O4 Fe3O4, a form of inorganic substances, has the chemical formula Fe3O4, black crystals with magnetic. Also known as Magnetic Iron Ore. Although it is not considered Fe (FeO2)2, iron oxide FeO2O3, or a mixture thereof, the compound can be described as ferrous oxide/iron oxide (FeO*Fe2O3). This substance cannot be dissolved in water, alkali solution or ethanol. Iron Oxide Fe3O4 from natural sources is insoluble when it comes into contact with acid solutions. However, the iron oxide (Fe3O4) can readily be oxidized in humid conditions to Iron Oxide Fe3O4 or Fe2O3. It’s used in paint, polish and manufacturing audiotapes and other telecommunications equipment.
What is Iron Oxide, Fe3O4 made of?

Schikorr reactions produce iron oxide Fe3O4. This reacts iron (II), hydroxylide (FeOH)2) to iron oxide (II, and III) (Fe3O4). Anaerobic conditions cause ferrous hydroxide(Fe(OH)2) to oxidize and turn into magnetite or molecular water. Schikorr’s reaction describes this process.

3Fe(OH)2-Fe3O4 + H2 + 2H2O

How do you distinguish Fe2O3 from Fe3O4 in

Fe2O3 vs Fe3O4 are two different minerals. Fe2O3 only has Fe2+ oxidation, while Fe3O4 has both Fe2+ and Fe3+.

What is Iron Oxide Fe3O4’s property?

Fe3O4 is an iron magnet with a Curietemperature of 858K. While many theories have been suggested for the cause of this phenomenon, none seem to fully explain it.

Although it is much more resistive than iron (96.1% nOm), Fe3O4 has an electrical resistance of 0.3 mOm, which is considerably lower than Fe2O3’s (approx. 10 kOm). This can be attributed to electron exchange among the FeII & FeIII centers of Fe3O4.

Fe3O4

Iron oxide (Fe3O4) commonly known by the names iron oxide black and magnetite can be employed in many fields.

Black pigments are also used, including Iron oxide (II and III), which is sometimes called Mars Black.

It’s used as a catalyst in the Haber process.

It is also used in water-gas shift reactions.

MRI scanners can use nanoparticles of Fe3O4 as contrasts.

The steel is protected from corrosion.

It’s an ingredient of thermite used in cutting steel.

This machine can create special coatings and magnetic recording material, as well as high gradient magnetic separators.
