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.

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.
Our experienced logistics team works closely with trusted carriers to ensure timely and safe delivery of our Reactive Alumina to our customers worldwide. We also offer customized packaging and shipping options based on our customers' specific needs.
With our efficient packaging and shipping process, you can trust that your Reactive Alumina will arrive at its destination in perfect condition, ready for use in your desired application.
