CAS 1309-37-1: Iron(III) oxide
Description:Iron(III) oxide, also known as ferric oxide, is a chemical compound with the formula Fe2O3. It is characterized by its reddish-brown color and is commonly found in nature as the mineral hematite. This compound is insoluble in water but can react with acids to form iron salts. Iron(III) oxide is known for its magnetic properties and is used in various applications, including as a pigment in paints and coatings, in the production of iron and steel, and as a catalyst in chemical reactions. It has a high melting point and is stable under normal conditions, making it suitable for high-temperature applications. Additionally, Iron(III) oxide can exist in several crystalline forms, including alpha, beta, and gamma phases, each with distinct properties. Its role in environmental processes, such as soil formation and as a component in rust, highlights its significance in both natural and industrial contexts. Safety considerations include its potential to cause respiratory irritation when inhaled in dust form, necessitating proper handling and protective measures.
