It is an inorganic compound with the chemical formula Fe3O4. This is a black magnetic crystal. Iron Oxide .

Fe3O4 Properties

The Fe3O4 black powder is a mixed iron valence oxide. It has a melting-point of 1597degC. It is insoluble with water but soluble with acid solutions. Magnetite is the natural form of Fe3O4 at room temperatures. It has a high conductivity and strong submagnetism.
The combustion of iron wires in oxygen produces ferroferric dioxide. By comparing the Gibbs energy produced by a standard mole of iron oxide with the Fe3O4 it is determined that Fe3O4 will have the highest thermodynamic stability.

Iron Oxide Fe3O4 Powder Properties And Preparation

Posted on by adminLeave a comment
Iron oxide Fe3O4 is an inorganic material with a chemical composition of Fe3O4. The magnetic black crystal is called magnetic iron dioxide.

Iron Oxide Fe3O4 Powder Properties

Ferric oxide cannot be dissolved in organic solvents, such as water or alkali solutions. Natural ferroferric dioxide is insoluble when dissolved in acid. It is readily oxidized in the humid air to iron oxide (Fe2O3).
The black Fe3O4 is an iron oxide with mixed valence, melting at 1597degC. It has a density of 5,18g/cm3. Fe3O4 Powder is insoluble with water but soluble with acid solutions. At room temperature, it appears as magnetite. It has a high conductivity and strong submagnetism.

Fe3O4 exhibits anti-corrosion properties. In the case of bluing steel parts, also known as baking blue and blue-burning, an alkaline oxidizing liquid is used to produce a blue-black Fe3O4 coating on the surface. It is used to improve corrosion resistance, aesthetics and gloss.

Iron Oxide Fe3O4 Powder Preparation

The main methods used to prepare nano-Fe3O4 are the hydrothermal method (solvothermal method), microemulsification and sol-gel.

1. Precipitation methods
The precipitation process is widely used to prepare nanoparticles because it is easy, inexpensive, yields a high purity product, has a uniform composition, is suitable for mass production, and can be done at large scales. The most common precipitation methods are co-precipitation and hydrolytic precipitation. Ultrasonic precipitation is also used, as well as alkoxide hydrogenation and chelate breakdown.

2. Hydrothermal (solvothermal method)
Hydrothermal reaction (solvothermal reaction) is the general term used for chemical reactions which are carried out under high pressure and temperature in fluids, such as aqueous (organic) solvents or steam. The Fe3O4 obtained by the hydrothermal process has a particle size that is small and uniform, it does not need high-temperature pretreatment to calcinate, and it can be doped with multivalent ions.

3. Microemulsification method
The microemulsification technique is a method of forming an emulsion from two immiscible solutions under the influence of surfactants. In this process, amphiphilic molecule divides the medium in tiny spaces that form a small reactor, where the reactants are able to react and form a solid. The microreactor limits the nucleation, growth of crystals, coalescence, agglomeration processes, so that nanoparticles are formed with a surfactant layer and a certain structure and morphology.

4. Sol-gel method
This method is based on the hydrolysis and oligomerization of metal alkoxides, which produces a uniform solution of metal oxides or hydroxides. The gel that results from this process can be concentrated into a clear liquid. The gel is dried, and then heat-treated in order to produce superfine powder.

About Iron Oxide Fe3O4 Powder
Iron oxide (II, III) (Fe3O4) is a highly insoluble and thermally stable iron source suitable for glass, optical and ceramic applications. Oxide does not conduct electricity. However, certain oxides of perovskite structure have conductivity in the cathodes of solid oxide fuel cells and oxygen generation systems. 

They are compounds containing at least one oxygen anion and one metal cation. They are generally insoluble in aqueous solutions (water) and are very stable, making them useful for ceramic structures, as simple as the production of clay bowls for advanced electronic devices, and for lightweight structural components in aerospace and electrochemical applications such as fuels Batteries in which they exhibit ionic conductivity. Metal oxides are basic high-purity (99.999%) iron oxide (FeO) anhydrides, so they can react with acids and strong reducing agents in redox reactions. Iron oxide can also be made into particles, nuggets, powders, sputtering targets, tablets, and Nanopowders. In most cases, iron oxide is usually available immediately. High purity, submicron and Nanopowder forms can be considered. Provide other technical, research, and safety (MSDS) information.

How is Iron Oxide Fe3O4 Powder Produced?
Iron tetroxide is produced by the Schikorr reaction. This reaction converts iron (II) hydroxide (Fe(OH)2) into iron oxide (II, III) (Fe3O4). Under anaerobic conditions, ferrous hydroxide (Fe(OH)2) oxidizes in water to form magnetite and molecular hydrogen. Schikorr ‘s reaction explains this process.
3Fe(OH)2→Fe3O4 + H2 + 2H2O
Ferrous Hydroxide Magnetite Hydrogen Water.
 
Applications of Iron Oxide Fe3O4 Powder
Triferric tetroxide, commonly known as iron oxide black, magnetite, and black iron oxide, can be used in many different fields, for example:

What is Nano Iron Oxide Fe3O4 Powder?

Posted on by adminLeave a comment
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 particles is smaller than 1 nanometer.
Powder of nano ferricoxide (Fe3O4) Magnetic and capable of generating directional movement in the external magnet field. When the particle size of the superparamagnetism is within a specified range, it can generate heat. It exhibits stable chemical performance.

Nano Iron Oxide Powder’s Physicochemical Property
Black Fe3O4 is an iron mixed-valence oxide with a melting temperature of 1597, and a density 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.
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 and then contacts with air Fe2O3 form. 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 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.
