What is Iron O2O4 ? Iron O3O4, a type inorganic substance, has the chemical formula Fe3O4, black with magnetic and is commonly known as magnetic iron dioxide. It cannot be considered Fe(FeO2)2, or as a mixture between iron oxide FeO2O3, although it can be roughly regarded as a compound from ferrous oxide, iron oxide (FeO*Fe2O3). The substance is not soluble in water, alkali solution or ethanol. Iron Oxide Fe3O4 from natural sources is insoluble when it comes into contact with acid solutions. However, the iron oxide (Fe2O3) can be easily oxidized to Iron Oxide Fe3O4 (Fe2O3) when exposed to air. It is often used in the production of audiotapes, telecommunications equipment, and as a polish.

How is Iron Oxide, Fe3O4, Produced?
Schikorr reactions produce iron oxide Fe3O4. This reaction turns iron (II), OH (Fe(OH),2) into iron oxide, II, III (Fe3O4). Anaerobic conditions cause ferrous hydroxide(Fe(OH),2) to oxidize in water and form magnetite, as well as molecular hydrogen. This process is described in Schikorr's reaction.
3Fe(OH)2-Fe3O4 + H2 + 2H2O
What is Fe2O3 and Fe3O4 different?
Fe2O3 vs Fe3O4 are two different minerals. Fe2O3 is paramagnetic and has only Fe2+ oxidation while Fe3O4 a ferromagnetic metal with both Fe2++ oxidation.
What are some properties of Iron Oxide Fe3O4?
Fe3O4 is ferrromagnetic and has a Curie Temperature of 858K. The Verwey transition is a phase transition that occurs at 120K. This transition is where there is a discontinuity between the structure, conductivity, and magnetic properties. While many explanations have been suggested, the effect has not been fully understood.
Although it has an electrical resistivity that is higher than iron (96.1% nO m), Fe3O4’s electrical resistance (0.3 mO.m) is much lower than Fe2O3’s (approx. 10 kO.m). This is due to electron exchange between FeII and FeIII centres in Fe3O4.
Iron Oxide, Fe3O4
Iron Oxide Fe3O4, also known as iron black, magnetite and black iron dioxide, can be used for many purposes.
Black pigments are also known as Mars Black, and Iron (II or III) oxide.
It is used in Haber processes as a catalyst.
It is used to produce the water-gas shifting reaction.
MRI scanning employs Fe3O4 Nanoparticles to contrast them.
It protects the steel against rusting.
It is an element in thermite and is used to cut steel.
It can also produce special coatings, high-grade magnetic separators and microwave absorption materials.

What is Nano Iron Oxide Fe3O4 Powder?

Introduction toNano Iron Oxide Powder
Iron dioxide Oder ferric oxide This is a type of inorganic material, and its chemical composition is 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 ferricoxide (Fe2O3) under humid conditions. It is often used as a polish and pigment, and in the manufacture 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.

The Physical and Chemical 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 easily soluble in acid. It can be found as magnetite in nature.
Fe3O4 can be produced when an iron wire is heated in oxygen.
Iron reacts with oxygen to form oxides on its surface. However, the oxide film is not uniformly made. Three oxide films can cover a piece low carbon steel: the metal contact FeO forms, while the air Fe2O3 contacts, and then the middle is 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 thick porous hydrated layer and an amorphous anhydrous coating on the metal's side.
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. The most common methods of preparing Fe3O4 are the precipitation method and hydrothermal (solvothermal), method. The focus is shifting to new methods of preparation, including the microwave, pyrolytic carbyl pre-body, ultrasonic, air oxidation, pyrolytic decrease method, and polyol removal method. There have been many breakthroughs in the production of Fe3O4, including new surfactants, preparation systems and methods. 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.
