Reactive Alumina (Activated High Alumina Micro-Powder) is a high-purity, reactive matrix filler engineered for advanced refractory castables and technical ceramics. Characterized by high alpha-alumina transformation and optimized particle size distribution, it fills micro-voids between aggregate grains, drastically reducing mixing water demand in unshaped castable systems.
In applications such as steel ladle castables, blast furnace iron runners, porous purging plugs, seating blocks, corundum self-flowing castables, and spray coatings, it promotes rapid solid-state sintering. This structural densification significantly maximizes cold/hot mechanical strength, thermal shock resistance, and molten slag erosion endurance under extreme operating conditions.
