Iron sesquioxide, also known as iron oxide or iron red, is a reddish-brown or black amorphous powder that is insoluble in water but soluble in acid. It comes in two variants: reddish-brown α-Fe2O3 is paramagnetic, while γ-Fe2O3 is ferromagnetic. In nature, it occurs in the form of hematite, which is the raw material for making iron.Iron trioxide in the industry has a wide range of applications, such as used as rubber, artificial marble, ground terrazzo colorant, plastic, asbestos, artificial leather, leather polishing paste and other colorants and fillers, precision instruments, optical glass polishing agents, and manufacturing of magnetic materials ferrite components of raw materials. In addition, it can also be used as an analytical agent, catalyst and polish, and is also used as an ingredient for pigments.
