| Particle distribution | -- | multimodal | -- | -- |
Engineering multimodal distribution: The multimodal grain distribution optimizes the filling of micropores in the refractory matrix, reduces the overall porosity, and can form a compact sintered structure.
Specialized MgO formula: A typical MgO content of 8.00% supports active matrix interactions, helping to improve the structural strength of the castable formula.
High pour flowability and low expansion: Optimized particle size and controlled surface area (BET 3.5-4.7 m²/g) provide excellent flow characteristics while maintaining low linear expansion during heating.
High and medium temperature strength: The controllable sintering activity promotes a reliable solid-state reaction pathway, improving the cold compression strength and hot fracture modulus in the medium temperature range.
Strict particle size control: Cilas laser diffraction verification ensures reliable D50 of 1.3-1.8 μm (typical 1.6 μm) and D90 of ≤ 8.5 μm, avoiding the generation of oversized aggregates in the mixing equipment.

Reactive alumina can serve as an essential active binder in ladle castables and iron runner linings, helping to prevent slag erosion of equipment and extend the service life of refractory materials. It can also be used for producing breathable bricks and seat bricks that require high density and precise dimensional stability. It can also be used for corundum self flowing castables and refractory spray coatings, achieving smooth pouring, minimal water demand, and high bonding durability.
Manufactured under strict ISO 9001, ISO 14001, and ISO 45001 standards, HUAO conducts complete chemical and physical testing on every lot to ensure consistent quality. The engineered particle packing of HA100 allows refractory manufacturers to achieve desirable rheological behavior with reduced mixing water, lowering drying times and thermal cracking risks. As a direct producer and exporter, HUAO offers steady volume supply, competitive factory-direct pricing, and dependable ocean freight support for global industrial clients.
