Aluminum Oxide Alumina
Aluminum oxide alumina, commonly referred to as alpha-alumina, is one of the main materials used in producing technical ceramics. It’s hard, wear-resistant, and offers protection from strong acids. Corundum has an extremely high melting point and is odorless; naturally occurring as corundum (red), ruby (pink), or sapphire (blue). Its crystal structure consists of hexagonally packed oxygen ions with only two-thirds of its interstices being filled by aluminum cations. Color Aluminum oxide (Al2O3) is a white, inert solid that is insoluble in water and an amphoteric compound; meaning it reacts with both acids and bases. Aluminum oxide has various applications: producing metallic aluminum, acting as abrasives for ceramic manufacturing and refractories […]
