Iron oxide
An inorganic substance having a chemical composition of Fe3O4. This is known as magnetic iron oxide.
Mixed valence iron oxide, black Fe3O4 has a melting point at 1597degC. It also has a density 5.99g/cm3. Fe3O4 is not soluble but can be dissolved in water. The natural form is magnetite at room temperatures. It is strong in sub-magnetism as well as high conductivity.
Fe3O4 exhibits anti-corrosion properties. To bluish steel parts, also known as blue-burning or baking blue, you use the alkaline-oxidizing solution’s oxidation effects to make a Fe3O4 coating on steel surfaces. It is useful to enhance corrosion resistance, aesthetics and gloss.
1. Precipitation method
Due to its ease of operation, low cost and uniform composition, the precipitation method is most popular for nanoparticle preparation. This method can also be used for large-scale production. The most common methods for precipitating are co-precipitation and hydrolytic precipitation.
2. Hydrothermal or Solveothermal method
Hydrothermal (solvothermal), chemical reaction can be described as any chemical reaction that is carried out using fluids. These include organic solvents (aqueous solutions) and steam at high pressure. This hydrothermal-prepared Fe3O4 has a small and relatively homogeneous particle size. It can also be used to dope multivalent ions.
3. Microemulsification method
Two immiscible solvents are used to create an emulsion. Surfactants act by dividing the fluid into smaller spaces. In order to create nanoparticles with condensed structure, morphology, and crystal growth through nucleation, crystal, co-creation and coalescence processes, the microreactor restricts them.
4. Sol-gel method
Hydrolysis and polymerization are used to make a homogeneous sol of metal oxides and metal hydroxides. This gel is then concentrated. For superfine oxide powder, heat is used to dry the gel.

Iron Oxide Fe3O4 Powder Properties
Iron oxide is not soluble in organic solvents, such as water and alkali solution. Ferroferric oxide, a natural iron oxide, is insoluble when it is in solution. However, in humid air, the oxide can easily be oxidized into iron oxide (Fe2O3).Mixed valence iron oxide, black Fe3O4 has a melting point at 1597degC. It also has a density 5.99g/cm3.
