What is it?
Fe3O4 Pulp
?
Fe3O4 (inorganic substance) has the chemical formula Fe3O4. It is a black magnetic crystal so it is sometimes called magnetic iron dioxide. It is not considered ferrous metaferrite [Fe(FeO2)2], and it cannot be regarded a mixture (FeO2O3) of iron oxide (Fe2O3). However it can be approximately referred to as ferrous oxygen. A compound consisting of iron oxide and iron (FeO*Fe2O3). This substance is insoluble when it comes into contact with water, alkaline solution, and organic solvents such ethanol or ether. Insoluble in acid solution, natural ferricoxide is easily oxidized into iron oxide (Fe2O3) when the environment is humid. It is commonly used as a pigment or polishing agent. However, it can also serve to manufacture audio tapes or telecommunications equipment.
Fe3O4 powder’s key features
Black Fe3O4 has a mixed valence of iron – a melting temperature of 1597degC and an average density of 5.18g/cm3. It is insoluble and soluble in water. It can be found as magnetite in nature.
Ferromagnetic or ferrimagnetic materials undergo a second order phase transition above Curie temperature, which transforms into paramagnetic compounds. The Curie temperature is 585 for Fe3O4. Ferric oxide is formed when iron wire is heated in oxygen. The standard mole for iron oxide is used to generate Gibbs energy. It is determined that Fe3O4 has a greater thermodynamic stability. This is why the product is Fe3O4. Iron oxides form when iron comes into contact air. This is because the chemical compositions of the oxide films are not uniform. Three oxide films can be applied to a piece low-carbon steel: FeO covers the metal, Fe2O3 covers the air and Fe3O4 covers the middle. The oxide film may consist of a mixture of solid saturated solutions of the three different oxides. The oxide film’s thickness can vary depending on how it is oxidized in different environments. The oxide film thickness on relatively pure iron in dry atmosphere is not more than 20 angstroms (1.angstrom = 0.1nm), but it can increase in thickness in humid environments, where rust spots are visible. This is when the oxides are deposited in layers. The layer closest to the metal is an dense amorphous-hydrous layer and the layer close to air is thick porous hydration. Fe3O4 and Hydrogen are formed when iron reacts to water vapor. Fe3O4 has an anti-corrosion property. To bluish steel parts (also known by bluing or baking blue), you use an alkaline oxidizing solution. The solution oxidizes to form a Fe3O4 blue-black/dark blue film on the steel parts. It is used to improve corrosion resistance, gloss, and aesthetics.
Fe3O4’s applications
1. Ferric oxide can be used as a magnetic material.
2. As a raw material for recording tapes or telecommunication equipment, a special made pure ferric dioxide is used.
3. This is used for topcoats or primers.
4. Ferric oxide is the main ingredient for the production iron catalyst (a catalyst).
5. In the field of domestic welding materials ferric oxide has been recognised. The production of welding wires and electrodes is still in its infancy and there is a lot of potential.
6. Ferric oxide is a strong magnet and has a high specific gravity, which makes it an excellent choice for wastewater treatment.
7. Also, ferric oxide can be used as a polishing and pigment agent.
