Multimodal Reactive Alumina with 8.00% MgO Content

Product Description

HUAO HA100 Reactive Alumina is a high-performance alpha-Al₂O₃ micro-powder engineered with a specialized multimodal particle size distribution, featuring a typical D50 of 1.6 μm and a BET surface area of 3.8 m²/g. Formulated with tightly controlled chemical impurities, optimizing particle packing, reducing mixing water demand, and enhancing matrix fluidity in advanced refractory formulations. It accelerates solid-state sintering to deliver superior mechanical strength and reliable protection against severe high-temperature environments.

Technical Parameters

Grain size can be prepared according to customer requirements.

Key Features

• Features a precisely engineered particle size distribution with a median D50 of 1.6 μm and D90 of 7.5 μm to maximize packing density.
• Maintained low sodium, silica, and iron oxide levels prevent high-temperature fluxing and chemical degradation in service.
• Controlled BET surface area averaging 3.8 m²/g provides ideal reactivity without excessive water absorption during mixing.
• Formulated with a typical 8.00% MgO content to promote beneficial spinel phase formation and volume stability during firing.

Advantages

• Superior Rheology and Water Reduction: Significantly reduced the requirement for mixing water while maintaining excellent fluidity, resulting in a denser casting matrix.
• Accelerated Solid-State Sintering: Promote early sintering and grain bonding at lower temperatures, significantly improving the mechanical strength at medium to high temperatures.
• Exceptional Slag Erosion Resistance: The dense microstructure and high purity provide a strong barrier against corrosive steel, slag, and chemical erosion.
• Enhanced Thermal Shock Stability: Minimize microcracks and structural degradation under rapid thermal cycling conditions in harsh industrial furnaces.

Applications

HUAO HA100 Reactive Alumina is a high-quality matrix filler for high-performance refractory castables, including ladle liners, blast furnace iron flow channels, porous blow plugs, seat blocks, corundum self flowing castables, and spray coatings. It provides excellent rheological control, high packing density, and outstanding slag erosion resistance in harsh high-temperature environments.
