Reactive Alumina is a high-performance, versatile material widely used in the refractory and advanced ceramics industries. It is a ultra-fine, highly reactive white powder produced through precise calcination and fine grinding of high-purity aluminum oxide, resulting in high specific surface area and exceptional sintering activity. Specifically engineered for demanding high-temperature applications, Reactive Alumina significantly improves matrix density, enhances cold and hot strength, and provides superior slag and corrosion resistance in refractory formulations.
High Al₂O₃ Content & Reactivity: Promotes excellent low-temperature sintering and dense matrix formation.
Optimized Particle Size Distribution: Fills micro-voids to increase packing density and reduce water demand in castables.
Enhanced High-Temperature Strength: Significantly boosts cold/hot modulus of rupture (MOR) and load-bearing capacity.
Superior Slag & Erosion Resistance: Protects refractory linings against harsh chemical and molten slag attacks.
Excellent Flowability & Workability: Improves rheological properties in refractory castables and ceramic slurries.
Customizable Particle Sizes: Can be processed into various particle sizes (e.g., sub-micron to fine powder) to meet specific customer requirements.
Overall, Reactive Alumina is a critical component for manufacturing top-tier refractory and ceramic products that withstand extreme thermal and mechanical stress. Contact us today to learn more about our Reactive Alumina powder and how HUAO can support your production needs.
