Reactive alumina is a porous and highly dispersed solid material with a large surface area, and its microporous surface has the characteristics required for catalytic action, such as adsorption performance, fluoride removal performance, drying performance, surface activity, excellent thermal stability, etc.
High-performance reactive alumina can bring the following benefits in the batching of unshaped refractory materials: increase the density, fluidity and strength, increase the amount of secondary mullite formation, etc., and reduce the amount of water capacity and porosity. In addition, it can also be used as an adsorbent and desiccant, with large water absorption, fast drying speed.
