Ferric oxide black by Research Lab Fine Chem Industries is a high grade reagent. Also known as iron(II,III) oxide, this is an oxide of iron. The reagent is available as a black powder which is insoluble in water. It has a melting point of 1538 C. Ferric oxide can be prepared by oxidizing ferrous hydroxide by water under anaerobic conditions. While it is stable under general conditions, this reagent is incompatible with strong oxidizing agents. CAS No. 1309-37-1 Quantity Provided: 500 gm per bottle Molecular formula: Fe2O3 Molecular weight: 159.69 Assay: 98 %Ferric oxide has a variety of applications in chemical and biological sectors. This reagent finds applications in the organic synthesis of various derivatives. Ferric oxide is often used as a black pigment. In the Haber process and the water gas shift reaction, it functions as a catalyst. It is additionally used as a contrast agent in MRI scanning in the form of nanoparticles. Ferric oxide is used along with sulfur and aluminium, in a specific type of thermite for cutting steel. This reagent is suitable for the industrial synthesis of products and research applications.
