Iron oxide is a compound with the formula Fe2O3. The mineral magnetite is a natural form of triiron oxide (of Fe3O4). It’s one of three iron oxides. Iron oxide is sometimes called hematite. It is the primary source of iron for steelmaking. It is also susceptible 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 many crystal forms. Iron has an octahedral six-coordinate structure among the main a or g configuration iron oxids. What is iron oxide pigment?
Iron oxide pigments refers to four main types of color pigments that are based upon iron oxides. These include iron oxide yellow, black and brown. Iron oxide is the predominant pigment (roughly accounting for all iron oxides). The category of iron pigments also includes mica ironoxide used as anti-rust pigment, magnetic iron oxide and other magnetic recording materials. 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, plastics and coatings. This is because it has high synthetic purity, uniform particles, a wide chromatogram and multiple colors. 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 is done with a fine powder of iron oxide, also known as “jeweler’s red rouge”, “red-rouge”, or “rouge”. Historically, it has been used to finish polishing metal jewelry and lenses. 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 slightly contaminate gold when polishing it. This can have a negative impact on the final product. 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 = yellow, b= red) in different hydrates.
3. Iron oxide is used as pigment. The names of the pigments are “Iron Oxide Brown 6”, “Iron Oxide Brown 7,” and “Iron Oxide Brown 101”. Pigment Brown 6 and Pigment Red 101 have been approved as cosmetic pigments 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 electricity throughout the entire year.”
