Key Features
The specialized doublet particle packing structure allows ultra-fine micro-grains to fit neatly into interstitial matrix voids, lowering porosity and ensuring high fired structural density.
An elevated MgO concentration drives active solid-state matrix reactions, supporting spinellization and early bonding to deliver superior high-temperature erosion resistance.
The controlled surface activity reduces water demand during mixing while preserving smooth flowability in castable slurries.
Controllable sintering activity promotes robust matrix consolidation, boosting intermediate mechanical strength and hot modulus of rupture.
Cilas laser diffraction verification ensures a stable median particle size of D50 1.7 μm and D90 9.0 μm for consistent processing performance.
Applications
Acts as a core reactive matrix component in steel ladle castables and iron runner linings, helping resist slag corrosion and thermal shock in hot metal zones.
Used in manufacturing high-performance breathable bricks, block bricks, and precast shapes where accurate dimensional stability and crack resistance are critical.
Incorporated into corundum self-flowing castables and refractory spray mixtures to deliver fast placement, reduced water requirements, and durable bond adhesion.
Why Choose HUAO
Manufactured in ISO 9001, ISO 14001, and ISO 45001 certified facilities, HUAO executes complete chemical and physical quality testing on every batch to maintain strict export consistency. The doublet particle sizing and lower surface energy of HA100S allow formulators to achieve high flowability with minimal water additions, lowering drying risks and improving final component yield. As a direct source producer, HUAO provides predictable supply capacity, direct pricing, and standardized international packaging tailored for sea freight.
Customization
HUAO provides adaptable packaging configurations to safeguard fine reactive powders against atmospheric humidity during ocean shipment. Options include 25kg multi-layer bags, 1000kg/1250kg jumbo bulk sacks with moisture-barrier polyethylene liners, and wooden-palletized shrink wrapping suited for international container transport.
FAQ
Q1: How does the 11.00% MgO content benefit HA100S performance in refractories?
A1: The typical 11.00% MgO addition facilitates matrix reactivity and in-situ spinel phase formation, improving high-temperature slag resistance, bond strength, and structural integrity under severe thermal conditions.
Q2: What is the main advantage of the doublet particle distribution in HA100S?
A2: The doublet distribution improves micro-particle packing density, which lowers overall water requirements during mixing and helps form a dense, low-porosity structure upon sintering.
Q3: What are the key chemical impurity limits for Reactive Alumina HA100S?
A3: HA100S maintains low impurity levels with typical values of 0.10% Na₂O, 0.04% Fe₂O₃, 0.10% SiO₂, and 0.03% CaO.
