What is Iron (III) Oxide? It is the inorganic compound with the formula Fe2O3. It occurs in nature as the mineral hematite, which serves as the primary source of iron for the steel industry. It is also known as red iron oxide, especially when used in pigments. Iron(III) oxide is often called rust, since rust shares several properties and has a similar composition; however, in chemistry, rust is considered an ill-defined material, described as hydrous ferric oxide.

Consistent Quality: We provide only high-quality Iron (III) Oxide, ensuring reliable and consistent performance for all applications.

Shipped from Manchester, UK Facility: Sourced and packaged in non-toxic, chemical-resistant containers to ensure safe handling and preserve product quality during transport.

Frequent Uses

Iron Production
The overwhelming application of iron(III) oxide is as the feedstock of the steel and iron industries, e.g., the production of iron, steel, and many alloys.

Pigments and Dyes
Sometimes used as a dark red pigment in certain industries.

Welding
Involved in the thermite reaction, used in welding steel. 

Catalysis
Utilised as a catalyst in several processes, including water treatment and cleaning exhaust gases.
