Product Description:
HUAO Reactive Alumina is an ultra-fine alpha alumina micro-powder engineered as an essential functional filler for advanced refractory systems and industrial ceramics. Featuring high chemical purity with strictly controlled impurities (Na2O <0.14%, Fe2O3 <0.04%, CaO <0.02%), it optimizes grain packing density and significantly lowers mixing water requirements.
This improves slurry fluidity, accelerates high-temperature solid-state sintering, and yields a dense microstructure. As a result, refractory castables, steel ladle linings, blast furnace runners, and spray coatings gain superior cold and hot mechanical strength, excellent thermal shock resistance, and long-lasting protection against severe molten slag and iron erosion.

Applications:
HUAO Reactive Alumina is an ultra-fine alpha alumina micro-powder engineered for high-performance refractory applications and monolithic castables. Featuring high chemical purity and controlled impurity levels (Na2O <0.14%, Fe2O3 <0.04%, CaO <0.02%), it serves as an essential matrix filler in steel ladle castables, blast furnace iron runners, porous purging plugs, seating blocks, and corundum self-flowing castables.
Customization:
By optimizing particle packing and reducing mixing water requirements, it enhances slurry fluidity, accelerates high-temperature sintering, and boosts thermal shock resistance. Flexible packaging options (25kg bags, 1250kg big bags) and customizable particle sizes are available under standard T/T payment terms.
During shipping, the bags or containers are carefully loaded onto pallets and secured with shrink wrap or straps to prevent any movement or damage. The pallets are then loaded onto trucks for domestic shipping or into shipping containers for international shipping.
Special care is taken to ensure that the product is properly cushioned and protected to prevent any breakage or damage during transportation. In addition, the shipping containers are clearly marked with the product name, quantity, and handling instructions.
