Fe3O4 powder 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. At room temperature, Fe3O4 appears in the form of magnetite in nature. It has strong submagnetism and high conductivity.
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 Fe3O4has the greatest thermodynamic stability, so the product is Fe3O4.
Fe3O4 has anti-corrosion effect. For example, the bluing of steel parts (also known as blue-burning and blue-baking) is to use the oxidation effect of alkaline oxidizing solution to form blue-black or dark blue Fe3O4 film on the surface of steel parts. Used to increase corrosion resistance, gloss and aesthetics.
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 reaction 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 has ferromagnetism, if the particle radius formed is at the nanometer level, it is called ferromagnetic particles.
1. It can produce magnetic recording materials, high gradient magnetic separators, microwave 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.
