Reactive Alumina is a premium alpha-phase alumina micro-powder specifically developed for high-performance refractories and technical ceramics. Its controlled micro-particle size distribution fills interparticle micro-voids between aggregate grains, optimizing matrix packing density and drastically reducing mixing water requirements in unshaped castable systems.
When integrated into high-temperature applications—including steel ladle linings, blast furnace iron runners, porous purging plugs, seating blocks, corundum self-flowing castables, and spray coatings—it accelerates solid-state sintering. This structural densification significantly boosts cold/hot mechanical strength, thermal shock endurance, and resistance to molten slag erosion, maximizing refractory service life under extreme operational conditions.
