Activated Alumina Powder

Activated Alumina Powder

Activated alumina powder is also known as the rho alumina powder, which is a alumina transition phase. Its main crystal phase is ρalumina base. Ρalumina is made by aluminum hydroxide through suspension roasting rapid dehydration and rapid cooling system. Its specific surface area is more than 260㎡/g, so it has strong flexibility , water absorption performance, and certain hydration. It replaces pure calcium aluminate cement in refractory castable binder, micro silicon powder and ultrafine alumina powder in adhesive and binder.
