Reactive Alumina
Reactive alumina is a highly dispersed porous material with large surface area, excellent adsorption performance, high surface activity, and strong thermal stability. It also offers good drying and fluoride removal properties. In unshaped refractory materials, reactive alumina helps improve density, fluidity, and strength while reducing water demand and porosity. It is also widely used as an adsorbent and desiccant due to its high water absorption and fast drying performance.
