HUAO Reactive Alumina HA160 is reactive alumina micro-powder engineered to satisfy rigorous rheology and structural performance demands in critical refractory applications. Manufactured in our ISO 9001, ISO 14001, and ISO 45001 certified production facility, HA160 features low impurity levels, fine particle sizing, and a well-balanced multimodal particle distribution. By combining a median particle size (D50) of 1.5 μm with a specific surface area (BET) of 4.1 m²/g, this micro-powder offers controllable sintering activity and low thermal expansion. As an established China reactive alumina supplier, HUAO provides HA160 directly to global B2B clients to improve slurry fluidity, boost medium-temperature strength, and enhance overall structural density in high-performance castable matrices.

Key Features
Engineered Multimodal Distribution: Multimodal grain packing allows sub-micron particles of varied sizes to fill micro-voids efficiently, promoting compact green body structures prior to firing.
Controlled Low Impurity Content: Low trace impurity levels—such as Fe₂O₃ (typical 0.03%, max 0.05%) and SiO₂ (typical 0.03%, max 0.10%)—help maintain refractoriness under severe thermal loads.
High Slurry Fluidity & Low Expansion: Optimized particle morphology and controlled BET surface area (typical 4.1 m²/g) reduce inter-particle friction during mixing, allowing low water additions and minimal firing expansion.
Enhanced Medium-Temperature Strength: Controllable reactivity accelerates early solid-state bonding, boosting intermediate and hot modulus of rupture (HMOR) in unshaped refractory products.
Precise Laser-Tested Sizing: Cilas diffraction monitoring ensures a reliable median particle size (D50: 1.1-1.9 μm, typical 1.5 μm; D90: 6.0-9.0 μm) for batch-to-batch consistency.
Applications
Ladle & Iron Ditch Castables: Functions as a critical active matrix binder in steel ladle castables and iron ditch castables, preventing premature slag penetration and improving hot erosion resistance.
Functional Refractory Components: Incorporated into breathable bricks, block bricks, and corundum self-flowing castables, where tight packing density and smooth placement are essential.
Refractory Spray Coatings & Monolithics: Applied in high-performance spray coatings and low-cement monolithic mixes to provide excellent adhesion, dense structural compaction, and stable volume behavior at high operating temperatures.
Why Choose HUAO
Certified Quality & Full Traceability: Produced under strict ISO 9001, ISO 14001, and ISO 45001 management systems, HUAO verifies chemical and physical metrics for every batch to ensure consistent performance.
Optimized Slurry Processing: The multimodal sizing and low water demand of HA160 help refractory compounders shorten drying schedules, lower installation water additions, and reduce thermal spalling risks.
Direct Factory Source with Global Logistics: As a direct manufacturer and exporter, HUAO guarantees bulk supply security, competitive factory pricing, and standardized export packaging for overseas maritime transit.
Customization
HUAO provides tailored packaging solutions to protect fine active powders against ambient humidity during international transit. Standard B2B options include 25kg multi-wall paper bags, 1000kg/1250kg jumbo bulk sacks with inner polyethylene moisture barriers, or customized palletized wrapping suited for global container logistics.
