“Reactive alumina, also known as activated or reactive aluminum oxide, is a high-purity form of alumina with high surface area and reactivity. It is produced by the controlled calcination of aluminum hydroxide or aluminum oxide at lower temperatures, which results in a porous and highly reactive material. Reactive alumina is widely used in the production of advanced ceramics, refractories, and catalysts. Its high reactivity makes it an essential component in applications requiring quick bonding and setting, such as in the manufacturing of high-performance refractories and as an active ingredient in catalyst supports in chemical processes.”
