What is Iron Oxide?
Iron oxide, also called ferric oxide, is an inorganic compound with the chemical formula Fe2O3. It is one of the three major oxides of iron, the remaining two being iron(II) oxide (FeO), which is the rare iron (II and III) oxide (Fe3O4), and also naturally takes place as the mineral magnetite. Since the mineral is referred to as hematite, Fe2O3 is iron's primary source for the steel industry and is readily attacked by acids. Often, iron oxide can be referred to as rust. This label is useful to some extent because rust shares many properties and has the same composition. But, in chemistry, rust is considered an ill-defined material, which can be described as Hydrous ferric oxide. Iron oxide is a compound made from iron and oxygen. There are 16 known iron oxides and oxyhydroxides, the most famous of which is rust, a type of ferric oxide. Iron oxides and oxyhydroxides are widespread and play important roles in many geological and biological processes. They are in hemoglobin and are used in iron ore, pigments, catalysts, and thermites. Iron oxide is a cheap and permanent pigment in paints, coatings, and colored concrete. Commonly available colors are on the "soil" edge of the yellow / orange / red/brown/black range. When used as a food coloring, the E number is E172.
Preparation of Iron Oxide
Iron(III) oxide is the oxidation of iron products, which it can be prepared in the laboratory by electrolyzing sodium bicarbonate solution, an inert electrolyte including an iron anode. One of the most important reactions of iron oxides is its carbothermal reduction that gives iron, used in steel-making. We can use this process to weld the thick metals, including rails of train tracks, with the help of a ceramic container to funnel the molten iron in between 2 sections of the rail. Thermite can also be used in making small-scale cast-iron sculptures, weapons, and tools. Partial reduction, along with the hydrogen compound at around 400 0C, will produce magnetite, which is referred to as a black magnetic material.
Polishing of Iron Oxide
A very fine ferric oxide powder is called "red rouge," "jeweler's rouge," or a rogue. It can be used to put the final polish on lenses and metallic jewelry pieces and, historically, as a cosmetic. This rouge cuts more slowly than a few modern polishes, like cerium(IV) oxide, but still, jewelers use it for the superior finish it can produce and in the optics fabrication. The rouge slightly stains the gold when polishing gold, contributing to the finished piece's appearance.
Price of Iron Oxide
Iron Oxide particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of Iron Oxide. A large amount of large amount will be lower. The Price of Iron Oxide is on our company's official website.
