CAS 1344-28-1: Alumina
Description:Alumina, chemically known as aluminum oxide, is a white, odorless powder with the formula Al₂O₃. It is a key component in various industrial applications, primarily due to its hardness and thermal stability. Alumina exhibits excellent electrical insulation properties and is chemically inert, making it resistant to corrosion and degradation in harsh environments. It has a high melting point, which contributes to its use in refractory materials. In addition to its structural applications, alumina is also utilized as an abrasive and in the production of aluminum metal through the Bayer process. The substance exists in several crystalline forms, including alpha (α-Al₂O₃) and gamma (γ-Al₂O₃), each with distinct properties and uses. Furthermore, alumina is commonly used as a catalyst support in chemical reactions and in the manufacture of ceramics and glass. Its biocompatibility also allows for applications in medical devices and implants. Overall, alumina is a versatile material with significant importance across various industries.
