Iron oxide is a compound with the formula Fe2O3. It is one of three iron oxides. The others are the rare ferrous oxid (of FeO) and triiron oxide (of Fe3O4) which occurs naturally as the mineral magnitite. Hematite, or iron oxide, is also known as hematite. Iron oxide is a main iron source in steelmaking. It is vulnerable to acidic corrosion. Iron oxide, also known as rust, is a common term. It is not always a problem because rust can have several similar characteristics. To chemists rust is a vague substance known as hydrated ferr oxide. Fe2O3 is available in several crystal forms. The main iron oxides of a and G configuration have an octahedral six-coordinate structure. What is iron oxide pigment?
Iron oxide pigments refers to four main types of color pigments made from iron oxides. These are iron oxide yellow, black and brown, as well as iron oxide red. Iron oxide is the predominant pigment (accounting for about 50% of all iron oxides). The category of iron pigments also includes mica ironoxide used as anti-rust pigment, magnetic ironoxide used as a recording material and magnetic ironoxide. Iron oxide is a large inorganic colour pigment, second only to titanium dioxide.
Synthetic iron oxide is a pigment that accounts for more than 70% of the iron oxides used. Synthetic Iron Oxide is widely used for building materials, paints, and plastics. This is because it has high synthetic purity, a uniform particle size and wide chromatogram. Electronics, tobacco, medicine, rubber, ceramics, ink, magnetic materials, papermaking, and other fields.

Applications and performance of iron oxide
1. Iron and Steel Industry: Iron oxide’s main application is in the steel and iron industry.
2. Surface polishing: ultra fine iron oxide powder, called “jeweler’s Rouge”, “red rouge”, and rouge in short. It has long been used to finish polishing metal jewelry, lenses and other items. Although iron oxide’s cutting speed is slower than that of some polishing agents used today (such as cerium dioxide), it is still employed in the optical industry and jewelry because it produces excellent finishes. Rouge will cause a small amount of contamination to the gold when polishing it. This can have an effect on the final product’s appearance. Rouge comes in powders and pastes as well as polishing cloths and solid sticks. Many other polishing products are referred to by the term “Rouge” even though they don’t contain iron oxide. Jewelers use ultrasonic cleansing to remove rouge residue from jewelry. For leather shaving, “scraping” compounds are used to achieve sharp edges for knives, hair straightening razers, or other edge tools.
Different colors of iron oxide (a = rust, b= yellow) in different hydrates.
3. Iron oxide can be used in cosmetics as a dye. Pigment Brown 6 and Pigment Red 101 have been approved for cosmetic use by the US Food and Drug Administration. For dental composites, titanium dioxide and iron oxide are combined as a pigment.
The world’s cheapest energy-storage device—iron-air batteries
Iron-air batteries that can be recharged at home are a cost-effective alternative to traditional power plants, and they only cost a fraction of what lithium-ion batteries do. Energy transition is dependent on finding ways to consolidate renewable energies. Long-term, cheap and safe batteries that store energy can be the key to the energy transition. This is because they are able to solve the variable nature of solar and wind energy.
The average storage cost of large lithium-ion cells was set at US$132-245/MWh by a French financial advisor in their industry standard annual report. Iron-air battery storage, at one-tenth that price, will be the cheapest energy storage solution available for a certain distance.
The personnel responsible for developing this battery stated: “This battery will be able to provide reliable, safe, and 100% renewable power throughout the entire year.”
