What kind of substance is Fe3O4?
Iron oxide is an inorganic substance with a chemical formula of Fe3O4. It is a magnetic black crystal, so it is also called magnetic iron oxide. It cannot be regarded as a "ferrite" [Fe(FeO2)2], nor can it be regarded as a mixture of ferrous oxide (FeO) and iron oxide (Fe2O3), but it can be regarded as a compound composed of low-priced iron And iron oxide (FeO·Fe2O3). The substance is insoluble in water, alkaline solutions, ethanol, ether and other organic solvents. The natural iron trioxide is insoluble in acid solution and is easily oxidized to iron oxide (Fe2O3) in humid air. Usually used as a paint and polishing agent, it can also be used to make tapes and telecommunications equipment.
What are the physical and chemical properties of iron trioxide?
The black Fe3O4 is a mixed valence oxide of iron. The melting point is 1597°C, and the density is 5.18g/cm3. Insoluble in water, soluble in acid solution. It appears in the form of magnetite in nature. Strong submagnetism and high conductivity.
Ferromagnetic and ferrimagnetic materials undergo a second phase transition above the Curie temperature to transform into paramagnetic materials. The Curie temperature of Fe3O4 is 585℃.
Fe3O4 has high conductivity, and the unusual electrochemical properties of Fe3O4 can be attributed to the electron transfer between Fe2+ and Fe3+.
Iron wire burns in oxygen to produce iron trioxide. Comparing the Gibbs free energy produced by standard moles of iron oxide, it can be concluded that Fe3O4 has the greatest thermodynamic stability, so the product is Fe3O4.
Overview of iron oxide Fe3O4
Iron oxide (II, III) (Fe3O4) 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, sub-micron and nano powder forms can be considered. Provide other technical, research, and security (MSDS) information. Fe3O4 is formed by Schikorr reaction. This reaction converts iron (II) hydroxide (Fe(OH)2) to iron oxide (II,III) (Fe3O4). Under anaerobic conditions, ferrous hydroxide (Fe(OH)2) is oxidized in water to form magnetite and molecular hydrogen. Skicor's response explained the process.
3Fe(OH)2 → Fe3O4 + H2 + 2H2O
Hydroxide magnetite hydrogen water.
Application of iron oxide Fe3O4
Iron Oxide Fe3O4 powder, usually called iron oxide black, magnetite and iron oxide black, can be used in many different fields, for example: iron oxide (II, III) is used as a black pigment, also known as Martian black.
Used as a catalyst in the Haber process.
Used for water gas shift reaction.
In contrast, Fe3O4 nanoparticles are used for MRI scans.
It can prevent steel from rusting.
It is a component in aluminate, used for cutting steel.
Iron oxide Fe3O4 powder is ferromagnetic. If the radius of the formed particles is in the nanometer range, they are called ferromagnetic particles.
1. It can produce magnetic recording materials, high gradient magnetic separators, wave absorbing materials, and special coatings.
2. It is widely used as a carrier of various pharmaceutical ingredients to form a magnetic targeted drug delivery system; used for the separation of magnetic immune cells and nuclear magnetic resonance imaging.
3. Used for precision instruments, gas sealing, vacuum sealing, etc.
