Iron oxide is a compound with the formula Fe2O3. It is one of three iron oxides. The others are the rare ferrous oxide (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 the primary source of iron for steelmaking. It is susceptible to acidic corrosion. Iron oxide, also known as rust, is a common term. It isn’t always a problem because rust can have several similar characteristics. To chemists rust is an undefined substance known as hydrated ferr oxide. Fe2O3 is available in a variety of crystal forms. The main iron oxides of a and G configuration have an octahedral six-coordinate structure.
What is iron oxide pigment?
Iron oxides pigments refers to four main types of color pigments based on iron dioxides. These are iron oxide red (red iron oxide), iron yellow (yellow iron oxide), iron black and iron brown. Iron oxide is a major pigment (representing approximately half of 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, coatings and plastics due to its low cost, high synthetic purity and non-toxicity. It also has multiple colors and a 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 – extremely fine iron dioxide powder is known as “jeweler’s rouge”, “red Rouge”, or simply “rouge”. It is used to polish lenses and metal jewelry. 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, pastes (with wax or grease binder), 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.

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 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 most affordable type of energy storage at a 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.”
