Introduction toNano Iron Oxide Powder

Iron dioxide


ferric oxide

This is an organic substance that is also called Fe3O4. It is a black crystal that has magnetic properties. This makes it also known as magnetic iron dioxide. Iron oxide is insoluble when mixed with water, alkali solution or ethanol. The natural ferricoxide is insoluble in acid solutions. It can also be oxidized to ferric oxide (Fe2O3) under humid conditions. It is often used in polish and pigment, as well to make audiotapes and other telecommunications equipment.

Ferric oxide has ferromagnetic property and is called “ferromagnetic particles” if the radius of the particle is smaller than 1 nanometer.

Powder of nano ferricoxide (Fe3O4)

Magnetic and capable of generating directional movement in the external magnet field. It exhibits superparamagnetism if its particle size falls within a specified range. In the external alternating electromagnetic fields, it can produce heat. It exhibits stable chemical performance.

Physicochemical properties of Nano Iron Oxide powder

Black Fe3O4 can be described as a mixed-valence ferrous oxide with a melting temperature of 1597 and density of 5.18g/cm3. It is insoluble with water, but it can be dissolved in an acid solution. It can be found as magnetite in nature.

Fe3O4 can be produced when an iron wire is heated in oxygen.

The iron forms oxides on the surface of its surfaces when it comes into contact air. However, the oxide film is not uniformly made. Three oxide films can cover a piece low carbon steel: the metal contact FeO forms, while contact with air Fe2O3 form, and the middle Fe3O4. Instead, it could be a mixture or saturated solid solutions of three different oxides that forms the oxide film.

However, oxide film thickness can vary according to environmental conditions. At room temperature the oxide thickness of relatively pure Iron in dry air is less than 20 angstroms. The oxide film thickness in humid air increases and can be observed as rust spots. The oxide layer stratifies at this point, with a dense, anhydrous, porous layer on one side and a thin, porous layer on another.

Iron reacts to water vapor to make Fe3O4 (and hydrogen).

Fe3O4 has anti-corrosion properties. One way to get the blue of iron or steel parts (also known by burning blue and baking bleu) is to use an oxidation of alkaline oxygenizing solution to form a layer on iron or steel parts of Fe3O4 of dark blue or blue-black Fe3O4 films. This will increase corrosion resistance, beauty and luster.

Nano Iron Oxide powder preparation

A large amount of literature has been published on nano-Fe3O4 preparation since 2013. However, some new methods have also been developed. There are several traditional methods to prepare Fe3O4: the precipitation method (solvothermal), micro emulsification and sol-gel methods. The focus is shifting to new methods of preparation, including the microwave, pyrolytic carbyl pre-body, ultrasonic, pyrolytic decrease method, pyrolytic reduction way, and polyol reduce method. There have been many breakthroughs in the production of Fe3O4. SDS, PEG CTAB and CTAB are not the only surfactants that have been developed. NSOCMCS has also reported polyacrylamide as a modifier. Ethanol and water system; n – propanol and water system; propylene glycol and water system.
