Iron oxide Oder ferric oxide This is a type of organic substance and has the chemical formula Fe3O4. This is a magnetic black crystal, also called magnetic iron dioxide. Iron oxide is not soluble in water or alkali solution. The natural ferricoxide is not soluble in acids and easily reacts with ferricoxide (Fe2O3) under humid conditions. It’s used in paint, polish and manufacturing audiotapes and other telecommunications equipment.
Ferric oxide, which has ferromagnetic property, is also known as ferromagnetic particles. The particle radius of ferric oxide should be less than a nanometer.
Powdered nano ferric oxide, Fe3O4. Magnetic and capable of generating directional motion in an external magnetic magnetic field. Superparamagnetism can be achieved when the particle sizes are in a specified range. It is also capable of producing heat in an external alternating magnetic field. It exhibits stable chemical performances.
Physical Properties of Nanoiron Oxide Powder
Black Fe3O4 is an iron mixed-valence oxide with a melting temperature of 1597, and a density 5.18g/cm3. It is not soluble but can be dissolved in water. It can be found as magnetite in nature.
Fe3O4 can be produced when an iron wire is heated with oxygen.
The oxide films are not evenly composed when iron is in direct contact with air. Three oxide films can cover a low carbon steel piece: the metal contact FeO forms while it is in contact with oxygen Fe2O3 forms. The middle Fe3O4 forms when it comes into contact with water Fe2O3. Instead, the film may form from a combination of saturated solid solutions and three oxides.
However, oxide thickness can vary according to environmental conditions. At room temperature the oxide thickness for relatively pure iron in dry atmosphere does not exceed 20 millimeters. (1 millimeter = 0.1 nanometer). The oxide film thickness in humid conditions can rise significantly and you will see rust spots. The oxide layer stratifies at this point, consisting of an amorphous andhydrous layer close to metal, as well as a porous, hydrated layer close to air.
Fe3O4 is formed when iron reacts to water vapor.
Fe3O4 can be used to enhance beauty and corrosion resistance.

Nano Iron Oxide powder preparation
A large amount of literature has emerged on nano-Fe3O4 preparation since 2013. Additionally, new methods of preparation have been developed. Preparation methods include hydrothermal (solvothermal), micro emulsification and precipitation. The focus is shifting to new methods of preparation, like the microwave method. There have been many breakthroughs in the production of Fe3O4. SDS and PEG have been identified as well as CTAB, CTAB and citric acid. NSOCMCS has also reported the use of polyacrylamide to modify surfactants. Ethanol-water system. n-propanol-water system. propylene glycol-water system.
Nano Iron Oxide powder has many applications
It is a magnetic multifunctional material. nano ferric oxide This has been extensively used in the treatment of tumors, as a microwave absorption material and catalyst carrier, cell separator, cell separation, magnetic record material, magnetic fluid, medicine, among other areas. You can use it in the following:
Useful as edible melanin
It is used to analyze pigments and other chemicals.
It is used in the primary raw material of an ammonia catalyst
It is used in the production of oil color and watercolor pigments. The coating industry is responsible for manufacturing anti-rust primers and paints. Concrete floor and tile construction. The electronics and telecommunications industries use magnetic steel as a catalyst plate for alkaline dry cells. It is used to detect steel flaws in machine-building.
It can be used to color capsules and tablet icing.
Useful for coloring coatings and plastic surfaces.
