Iron oxide (II, III) is a commonly used magnetic material

Overview of Iron oxide(II, III)

Iron oxide (II, III) is a compound with the chemical formula Fe3O4. It exists in nature as the mineral magnetite. It is one of a variety of iron oxides, the others are rare iron (II) oxide (FeO) and iron (III) oxide (Fe2O3), also known as hematite. It contains both Fe2 + ions and Fe3 + ions and is sometimes called FeO∙Fe2O3. This iron oxide is black powder in the laboratory. It is permanent and ferrimagnetic but is sometimes incorrectly described as ferromagnetic. Its most widespread use is as a black pigment. For this reason, it is synthetic, not extracted from natural minerals, because its particle size and shape can be changed by production methods.

Iron oxide (II, III) cannot be partial to "ferrous ferrite" [Fe(FeO2)2], nor can it be called a part of ferrous oxide (FeO) and iron oxide (Fe2O3), but it can be viewed approximately The substance is insoluble in water, alkali solutions, ethanol, ether and other organic solvents. Natural Iron oxide is insoluble in acid solution and easily oxidized to iron oxide (Fe2O3) in the air when placed in the state.

Ferroferric oxide has ferromagnetism. If the particle size is at the nanometer level, it is called ferromagnetic particles. Three oxides of iron: ferrous oxide (FeO), iron oxide (Fe2O3), and ferric oxide (Fe3O4).

At present, the mechanism of the method for preparing magnetic Fe3O4 nanoparticles has been thoroughly studied, and it can be divided into two types. One is to use divalent and trivalent iron salts to obtain magnetic Fe3O4 nanoparticles through the reaction under certain conditions; the other is to use trivalent iron salts, which are transformed into trivalent hydroxides under certain conditions, and finally through baking Dry calcination and other means to obtain magnetic Fe3O4 nanoparticles.

Applications of Iron oxide(II, III)

As we all know, when the size of the particles is reduced to the nanometer level, due to the small size effect, surface effect, quantum size effect and macroscopic quantum tunneling effect of nanoparticles, nano-ferric oxide FE3O4 is different from conventional bulk materials. The special magnetic properties. This also makes it have special applications in industries, biomedicine and other fields.

Biomedicine  

Fe3O4 is widely used in many fields of biomedicine, such as magnetic resonance imaging, magnetic separation, and targeted drugs due to its stable material properties, good biocompatibility, high strength, and no toxic side effects. Carrier, tumor hyperthermia technology, cell labeling and separation, as well as research as an enhanced imaging agent, contrast agent, and repair surgery for retinal detachment

Magnetic fluid

The magnetic fluid is a new type of functional material. It will be a highly stable colloidal solution composed of numerous nano-scale ferromagnetic or ferrimagnetic particles dispersed in a liquid carrier liquid. The particles and carrier liquid pass through a surfactant The mixed magnetic liquid can exist stably for a long time even under the action of the gravitational field, electric field and magnetic field, without precipitation and separation

Catalyst carrier

Fe3O4 particles are used as catalysts in many industrial reactions, such as the production of NH3 (Haber's ammonia production method), high-temperature water-gas transfer reactions, and natural gas desulfurization reactions. Due to the small size of Fe3O4 nanoparticles, the large specific surface area, and the poor surface smoothness of the nanoparticles, uneven atomic steps are formed, which increases the contact surface for chemical reactions.

Magnetic recording material

Another important use of nano-Fe3O4 magnetic particles is to make magnetic recording materials. Nano Fe3O4 due to its small size, its magnetic structure changes from multi-domain to single-domain, with very high coercivity, used for magnetic recording

Magnetic health

The human body has a biological magnetic field, and every cell of the human body is a magnetic micro-unit, so changes in the external magnetic field will affect the physiological functions of the human body. According to reports, the magnetic field has an effect on the human nervous system, heart function, blood composition, vascular system, blood lipids, hemorheology, immune function, endocrine function and activity.
