Doublet HA100S Reactive Alumina for Low Water Demand

Product Description

HUAO HA100S Reactive Alumina is a premier, high-performance α-Al₂O₃ micro-powder engineered with an advanced doublet particle size distribution. Featuring a median particle size (D50) of 1.7 μm and an optimized BET surface area of 2.3 m²/g, HA100S is specifically formulated to bridge interstitial voids in advanced refractory formulations.

Enhanced with a typical 11.00% MgO content and strictly controlled trace impurities, this specialized reactive powder delivers exceptional rheology control, reduces mixing water requirements, and accelerates solid-state sintering to build unbreakable matrix density in extreme high-temperature applications.

Technical Parameters

Grain size and distribution can be custom-prepared according to client specifications.

Key Features

• Designed with a specialized doublet size distribution (D50 of 1.7 μm and D90 of 9.0 μm) that optimizes interstitial packing between aggregate grains.
• A controlled surface area of 2.3 m²/g ensures high matrix reactivity while preventing excessive water absorption during wet mixing.
• Formulated with a typical 11.00% MgO content to promote beneficial spinel phase formation and volumetric stability during high-temperature firing.
• Maintained low sodium, iron, and silica levels prevent high-temperature fluxing and chemical degradation under severe thermal loads.

Advantages

• Dramatic Reduction in Mixing Water Demand: Excellent rheological control can significantly reduce the moisture content in the castable mixture without changing the flowability of the casting.
• Accelerated Solid-State Sintering: Promote early grain bonding and matrix densification at lower sintering temperatures, and improve mechanical strength.
• Exceptional Slag Erosion Resistance: The combination of high purity and optimized magnesium oxide enrichment forms a powerful chemical barrier against corrosive steel and slag erosion.
• Enhanced Thermal Shock Stability: Minimize microcracks and structural degradation to ensure long-term reliability.

Applications

HUAO HA100S Reactive Alumina is a high-quality matrix filler for high-performance refractory castables, including ladle liners, blast furnace iron flow channels, porous purge plugs, seat blocks, corundum self flowing castables, and spray coatings. It provides good rheological control, high bulk density, and excellent slag erosion resistance in harsh high-temperature environments.
