High-performance modern water-purifying alumina can bring the following benefits in the amorphous refractory formulation: increase the density, fluidity, strength, increase the amount of secondary mullite, and reduce the water addition and porosity. In addition, activated alumina can also be used as adsorbent, desiccant, large water absorption, fast drying speed, regenerative (400-500K baking) and water absorption without swelling, no cracking, no deformation.
