Product Description:
HUAO Reactive Alumina is an advanced calcined micro-powder engineered to optimize the rheological and thermo-mechanical properties of unshaped refractories. Characterized by its high alpha-alumina conversion and controlled multi-modal particle size distribution, it acts as an exceptionally efficient matrix filler for low and ultra-low cement castables.
By significantly reducing water demand while maintaining excellent flowability, it maximizes the structural density of steel ladles, iron troughs, and purging plugs. This engineered densification translates to outstanding resistance against severe thermal cycling, mechanical abrasion, and molten slag penetration, ensuring maximum operational reliability in extreme high-temperature environments.

Applications:
HUAO Reactive Alumina (Zibo, Shandong) is an ISO9001, ISO14001, and ISO45001 certified alpha-alumina micro-powder engineered for high-performance refractory systems and technical ceramics. Formulated with controlled micro-particle distribution and high sintering reactivity, it optimizes grain packing density and minimizes water demand in castable systems.
It is critical for manufacturing steel ladle linings, blast furnace iron runners, porous purging plugs, seating blocks, corundum self-flowing castables, and spray coatings. By filling micro-voids, it drastically boosts mechanical strength, thermal shock endurance, and resistance to molten slag penetration.
Tailored particle sizing, custom blending, and flexible packaging (25kg bags, 1,250kg bulk, Jumbo BB) are available.
Customization:
We offer fully customized solutions tailored to your specific processing needs, including custom particle size distributions, specialized blending, and flexible packaging options (25kg bags, 1,250kg bulk bags, or Jumbo BB bags).
