Reactive Alumina For High Performance Refractory Products Including Ladle Castables With 0.4 - 0.6 Cm³/G Pore Volume

Product Description:

Reactive Alumina is a premium alpha-phase alumina micro-powder engineered for advanced refractories and technical ceramics. Featuring high purity, tailored micro-particle sizing, and superior sintering reactivity, it optimizes matrix packing density and fills interparticle micro-voids in unshaped castable formulations.

When integrated into high-temperature systems—such as steel ladle castables, blast furnace iron runner materials, porous purging plugs, seating blocks, corundum self-flowing castables, and protective spray coatings—it drastically reduces mixing water requirements. This structural densification boosts cold and hot mechanical strength, thermal shock endurance, and resistance to molten slag erosion, significantly extending refractory service life under extreme operational conditions.

Technical Parameters:

Applications:

HUAO Reactive Alumina (Zibo, Shandong) is a premium alpha-phase alumina micro-powder engineered for high-performance refractories and technical ceramics. Featuring high purity, tailored particle sizing, and high sintering reactivity, it optimizes matrix packing density and fills micro-voids between aggregate grains.

In unshaped castable systems—including steel ladle linings, blast furnace iron runners, porous purging plugs, seating blocks, and corundum self-flowing castables—it significantly reduces mixing liquid requirements. This structural densification enhances cold and hot mechanical strength, thermal shock endurance, and molten slag erosion resistance, maximizing refractory service life under extreme high-temperature industrial conditions. Flexible packaging and custom specifications are available.

Customization:

HUAO Reactive Alumina (Zibo, Shandong) is a premium raw material engineered for high-performance refractories and technical ceramics. Certified under ISO9001, ISO14001, and ISO45001 standards, it features high alpha-phase purity, optimized micro-particle packing, and superior sintering reactivity.

It is an essential matrix additive for manufacturing steel ladle castables, blast furnace iron runner castables, purging plugs, seating blocks, corundum self-flowing castables, and spray coatings. By filling interparticle micro-voids, HUAO Reactive Alumina reduces mixing water requirements, significantly boosting matrix density, cold/hot mechanical strength, thermal shock stability, and slag erosion resistance.

Flexible packaging options (25kg bags, 1,250kg bulk bags, Jumbo BB) and customizable particle specifications are available.
