HUAO HA120 Reactive Alumina Micro-Powder is a high-purity alpha-alumina (α-Al₂O₃) engineered with a tailored doublet (bimodal) particle size distribution for advanced refractory castables and technical ceramics. Featuring a median particle size of D50 = 1.2 μm, a typical BET surface area of 4.8 m²/g, and strictly controlled chemical impurities (Na₂O ≤ 0.12%, SiO₂ ≤ 0.07%, Fe₂O₃ typical 0.03%), HA120 delivers an optimal balance between matrix fluidity and sintering activity. By optimizing grain packing efficiency and significantly reducing mixing water demand, HA120 promotes rapid solid-state sintering, providing superior mechanical strength, high thermal shock endurance, and robust protection against aggressive molten slag erosion.

Reactive Alumina HA120 enhances matrix structural density and superior slag resistance under severe thermal loads, while providing outstanding resistance to thermal shock and mechanical erosion under continuous molten metal flow. Engineered for demanding functional refractories, it is ideal for porous purging plugs, seating blocks, and shrouds requiring dense microstructures. In gunning and shotcreting applications, it optimizes slurry rheology, imparting excellent self-flowing capability while minimizing material rebound.
Operating in full compliance with ISO 9001 (QMS), ISO 14001 (EMS), and ISO 45001 (OHSMS) certified management systems, HUAO leverages over a decade of international B2B export expertise to ensure uncompromising quality control. We enforce hands-on, on-site production monitoring to guarantee exceptional batch-to-batch consistency in particle size distribution (PSD) and chemical purity. Direct-from-factory manufacturing delivers complete end-to-end traceability, reliable long-term supply capacity, direct-factory cost efficiency, and tailored technical support.
HUAO HA120 Reactive Alumina Micro-Powder is supplied in standard 25 kg moisture-proof multi-ply bags or heavy-duty 1,000 kg / 1,250 kg bulk jumbo bags (ton bags) fitted with protective polyethylene inner liners to prevent moisture absorption and contamination during maritime transport. To support specific processing conditions and automated dosing systems, HUAO provides tailored customization services—including targeted particle size distributions, controlled top-size limits, specialized palletization, extra protective outer wrapping, and private-label OEM export packaging upon request.
We also offer a complete line of high-purity alumina products. If you would like to explore our White Fused Alumina, please contact our technical sales team.
