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] nor can it be considered a mixture (FeO2O3) of iron oxide and ferrous dioxide. However, it could be considered 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 ether and ethanol. Insoluble in acid solution, natural ferricoxide is easily oxidized into iron oxide (Fe2O3) when the environment is humid. It is used mostly as a pigment or polishing agent. However, it can also serve to manufacture audio tapes and telecommunications equipment.
Fe3O4 powder’s key features
Black Fe3O4 or mixed valence ox of iron is a mixed valence ox with a melting temperature of 1597degC, and a density at 5.18g/cm3. It is insoluble and soluble in water. It can be found as magnetite in nature.
Ferromagnetic and ironimagnetic compounds undergo a second order phase transition above Curie temperature to transform into paramagnetic substance. The Curie temperature is 585 for Fe3O4. Ferric oxide is formed when iron wire is heated in oxygen. Comparing the standard mole iron oxide to produce Gibbs free energy, it was found that Fe3O4 has a greater thermodynamic stability. 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 according to the environmental conditions that occur during oxidation. At room temperature, the oxide film thickness on relatively pure iron is not more than 20 angstroms (1.angstrom = 0.1nm). But, it can be seen that the oxide film thickness increases in humid air. Rust spots can also be 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 result is a Fe3O4 coating 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 primers or topcoats.
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.
