Fe2O3 is a mineral called hematite which is the main source of iron in the steel industry

Overview of Iron Oxide Fe2O3

Iron Oxide Fe2O3 is an important n-type semiconductor (Eg = 2.1eV), non-toxic, cheap and stable, widely used in catalysts, sensors, etc. High-purity ferric oxide is used in electronic components and magnetic recording materials. Iron (III) oxide usually refers to iron oxide. Iron (III) oxide is an inorganic substance with the chemical formula Fe2O3. It is a red or dark red amorphous powder. The relative density is 5~5.25, and the melting point is 1565°C (decomposition at the same time). Insoluble in water, soluble in hydrochloric acid and sulfuric acid, slightly soluble in nitric acid.

 Iron oxide (III) or Fe2O3 is an inorganic compound with the molecular formula Fe2O3. It is one of the three main oxides of iron, and the other two are rare iron oxide (FeO). Iron oxide (II, III) (Fe3O4) also naturally exists in the form of the mineral magnetite. Fe2O3 is a mineral called hematite, which is the main source of iron in the steel industry. Fe2O3 is easily corroded by acid. Iron (III) oxide is often referred to as rust. To some extent, this mark is useful because rust has multiple properties and similar components. However, chemically, rust is considered an unclear material. It is hydrated iron oxide.

 The diameter of iron (III) oxide nanoparticles is between about 1 and 100 nm. The two main types are magnetite and its oxidized form of maghemite. Iron (III) oxide nanoparticles are classified as irritants, which may cause skin, eye and respiratory tract irritation.

Applications of Iron Oxide Fe2O3

Iron oxide (III) has strong hiding power and tinting power and has no oil permeability and water permeability. Stable in the atmosphere and sunlight, resistant to polluting gases, high temperature and alkali. The dry processed products of this product have coarse and hard crystal particles, which are suitable for magnetic materials, polishing and abrasive materials. Wet-processed products have fine and soft crystal particles, which are suitable for coating and ink industries.

Magnetic material

Due to its special superparamagnetism, magnetic iron oxide particles have a wide range of applications in giant magnetoresistance, magnetic fluid and magnetic recording, soft magnetism, permanent magnetism, magnetic refrigeration, giant magnetoresistance materials, magneto-optical devices, and magnetic detectors. Application prospects. Videotapes generally use acicular iron or iron oxide magnetic ultrafine particles, and nano-iron oxide is a new type of magnetic recording material. Soft ferrites have been widely used in the fields of radio communication, radio and television, automatic control, space navigation, radar navigation, measuring instruments, computers, printing, household appliances, and biomedicine.

Pigment field

As a pigment, iron oxide is widely used in high-end automotive coatings, architectural coatings, anti-corrosion coatings, powder coatings. It is a good environmentally friendly coating. Using iron oxide as a pigment not only maintains the good heat resistance, weather resistance and UV absorption of general inorganic pigments. And other advantages, it can be well dispersed in the oily carrier, and the coating or ink prepared with it has satisfactory transparency. The use of iron oxide with semiconductor characteristics to make paint, due to its high electrical conductivity, can play a role in electrostatic shielding.

Iron oxide is a commonly used colorant in glass production. Iron oxide colored glass can absorb both ultraviolet and infrared, so it is widely used in the manufacture of heat-absorbing glass, sunglasses glass, industrial protective glasses glass and military anti-infrared coatings. At the same time, it has the function of low price, heat absorption and ultraviolet ray absorption.

Catalysis

α-Fe2O3 powder particles have a huge specific surface area and significant surface effect, making it a very good catalyst. Due to the small size of iron oxide particles, the surface area occupies a large volume percentage, the bonding and electronic states on the surface are different from those inside the particles, and the coordination of surface atoms is different, which leads to an increase in active sites on the surface. The catalyst made of nano α-Fe2O3 particles has higher activity and selectivity than ordinary catalysts, and has a long life and is easy to operate. Nano-α-Fe2O3 has been directly used as a catalyst for the oxidation, reduction and synthesis of high molecular polymers. When it is used in petroleum refining, it can increase the cracking speed by 1 to 5 times. Using it as a solid combustion catalyst can make the combustion speed faster. The burning speed of ordinary combustion agents is increased by 1 to 10 times, which is very beneficial to the manufacture of high-performance rockets and missiles.

Biomedicine and other fields

Nano-iron oxide plays an important role in the fields of medicinal capsules, drug synthesis, biomedical technology and so on. In addition to its applications in magnetic materials, pigments, catalysis, and biomedicine, α-Fe2O3 also has broad application prospects in other fields. For example, nano-scale iron oxide has a good adsorption effect on Cr(VI), with high adsorption efficiency, short adsorption time, and can be recycled and reused. It has a certain application value for treating Cr(VI) in environmental sewage; The gas-sensitive material made of nano-α-Fe2O3 has the characteristics of fast response, strong selectivity, high sensitivity and good stability; when preparing transparent iron oxide, if the content of arsenic and heavy metals is strictly controlled, it can be used in food, cosmetics and other industries; because transparent iron oxide has the characteristics of transparent coloring, acid and alkali resistance and non-toxicity, it can also be used as a coating for the inner wall of can lids.
