HUAO Reactive Alumina is a high purity, ultra-fine white alpha alumina micro-powder engineered for high-performance refractory systems. Characterized by low impurity levels (Na2O ≤ 0.10%, CaO ≤ 0.03%, Fe2O3 ≤ 0.04%) and customizable particle size distributions, it serves as an essential functional matrix filler in steel ladle castables, blast furnace iron runners, porous purging plugs, seating blocks, corundum self-flowing castables, and refractory spray coatings.
By optimizing particle packing and significantly reducing mixing water demand, it enhances slurry fluidity, accelerates high-temperature sintering, and maximizes cold and hot mechanical strength, thermal shock resistance, and slag erosion protection.

HUAO Reactive Alumina is a critical matrix micro-powder engineered for high-performance shaped and unshaped refractories. Optimized for dense particle packing, it reduces mixing water demand and improves workability in steel ladle castables, blast furnace iron runners, porous purging plugs, seating blocks, corundum self-flowing castables, and spray coatings.
During high-temperature thermal processing, it accelerates solid-state sintering to form a tightly bonded ceramic microstructure. This delivers outstanding cold and hot mechanical strength, superior thermal shock resistance, excellent wear resistance, and reliable, long-lasting protection against aggressive molten metal and slag erosion in severe industrial furnace environments.
HUAO offers customized reactive alumina tailored to your exact process needs. We precisely control particle size distributions (PSD) and adjust chemical purity—including ultra-low Na2O, Fe2O3, and CaO levels—ensuring optimal packing density, tailored rheology, and peak performance for your specific refractory or ceramic formulations.
Reactive Alumina is typically packaged and shipped in the following ways:
When shipping reactive alumina, it is important to ensure that the packaging is properly labeled and secured to prevent any damage during transit. The product should also be stored in a dry and well-ventilated area to maintain its quality and effectiveness.
For international shipping, the product may be subject to customs regulations and may require additional documentation or labeling. It is important to consult with the shipping company and adhere to all necessary guidelines and regulations to ensure a smooth and timely delivery.
