Product Description:
Reactive Alumina Powder is an essential raw material engineered for advanced refractories and technical ceramics. Featuring high alpha-phase purity, tailored micro-particle size distribution, and superior sintering reactivity, it optimizes particle packing density and fills micro-voids between aggregate grains.
In low-cement and ultra-low-cement castable formulations—such as steel ladle linings, blast furnace iron trough materials, porous purging plugs, seating blocks, and corundum self-flowing castables—it drastically reduces mixing water requirements. This improves matrix flowability, accelerates solid-state sintering, and maximizes bulk density.
Consequently, Reactive Alumina significantly enhances cold and hot mechanical strength, thermal shock resistance, and molten slag erosion resistance, ensuring prolonged service life and structural integrity under extreme high-temperature industrial conditions.
