HUAO HA250 Reactive Alumina Micro-Powder is a premium, ultra-fine alpha-alumina engineered for high-performance refractories and advanced technical ceramic formulations. Featuring high chemical purity with low soda (Na₂O ≤ 0.14%) and ultra-low silica (SiO₂ ≤ 0.07%), HA250 is characterized by a BET surface area of 3.0 m²/g and a median particle size of D50 = 2.5 μm with a specialized bimodal (doublet) particle size distribution. This tailored grain sizing optimizes particle packing density within refractory matrixes, reducing water demand in castables while accelerating rapid thermal sintering to significantly boost mechanical strength, thermal shock endurance, and molten slag erosion resistance.

Note: Custom grain sizes can be prepared according to specific client process requirements.
Engineered to withstand extreme thermal loads and continuous liquid iron erosion, HUAO HA600 Reactive Alumina increases mechanical durability, thermal shock stability, and slag corrosion resistance. It optimizes the rheology, flowability, and placement adhesion of unshaped refractory mixes—making it the ideal solution for porous purging plugs, seating blocks, and shrouds requiring ultra-dense microstructures. Furthermore, as a reactive sintering additive for technical ceramics, HA600 delivers high green density, ultra-low water demand, and exceptional sintering shrinkage control.
Operating under ISO 9001, ISO 14001, and ISO 45001 certified management systems, HUAO brings over 10 years of international B2B export expertise to ensure uncompromising product quality and seamless order execution. Every batch undergoes rigorous quality control, including laser particle size distribution (Cilas) and full chemical analysis. Backed by integrated, end-to-end production lines, we deliver consistent volume supply, direct factory cost advantages, and attentive, long-term technical support.
HUAO HA250 Reactive Alumina is available in standard 25 kg moisture-proof bags or heavy-duty 1,000 kg / 1,250 kg jumbo bags (ton bags) fitted with protective polyethylene inner liners. Customized grain size distributions and export packaging are available upon request.
