Iron oxide Chemical Properties,Usage,Production

Description

As the mineral hematite, Iron oxide is the main source of iron for the steel industry. Iron oxide is easily attacked by acids. Iron(III) oxide is regularly called rust, and to some extent this label is useful, as rust shares several properties and has a comparable composition. To a chemist, though, rust is thought of as an ill-defined material, described as hydrated ferric oxide. Fe2O3 can be formed in various polymorphs.

Uses

iron oxide (iron oxide black, red, or yellow) is an inorganic compound frequently used to add color to cosmetics. It may have some slight sun screening ability. Iron oxide can vary in color from red to brown, black to orange or yellow, depending on the purity and amount of water added.

Uses

Iron Oxide is a trace mineral used as a pigment and colorant. it is used to color pet food.

Definition

Pigments composed mainly of ferric oxide (Fe2O3).

Industrial uses

Iron oxide is the fine red abrasive component of rouge. Like tripoli, rouge is blended with various soft binders into a cake form. It is used to polish high noble metal alloys such as yellow gold alloys.

Solubility in organics

Iron(III) oxide is insoluble in water but dissolves readily in strong acid, for example, hydrochloric and sulfuric acids. It likewise dissolves well in solutions of chelating agents such as EDTA and oxalic acid. Heating iron(III) oxides with other metal oxides or carbonates yields materials known as ferrates (ferrate (III)).
