Sintered Tabular Alumina Aggregate with Al₂O₃ ≥ 99.2%, Bulk Density ≥ 3.50 g/cm³, Low Porosity, and High Scour Resistance

HUAO Tabular Alumina is a pure, dense, sintered alpha-alumina aggregate produced from finely ground aluminum oxide powder through rolling forming and ultra-high temperature sintering. Manufactured in our ISO 9001, ISO 14001, and ISO 45001 certified production facility, HUAO operates two dedicated tabular alumina production lines yielding an annual output of 50,000 tons.

The product features fully developed hexagonal tablet-shaped alpha-alumina crystals with key performance metrics exceeding national standard benchmarks. Characterized by high purity (Al₂O₃ ≥ 99.2%), low silica (SiO₂ ≤ 0.09%), and low iron (Fe₂O₃ ≤ 0.02%), our factory-direct aggregate delivers outstanding fire resistance, high corrosion resistance, and stable volume performance under elevated operating temperatures.

• Scalable Manufacturing & Reliable Supply: Operating two advanced production lines with an annual capacity of 50,000 tons under ISO 9001, ISO 14001, and ISO 45001 management systems ensures batch-to-batch consistency and continuous delivery for bulk international orders.
• Superior Fire & Scour Resistance: Completely sintered alpha-alumina micro-crystals provide high resistance to physical abrasion, hot slag erosion, and high-temperature thermal loads.
• Lower Compounder Formulation Costs: Low water absorption (≤ 1.5%) and regular grain morphology allow refractory formulators to minimize binder consumption while achieving optimal slurry flowability.
• Strict In-House Quality Control: Key performance indices exceed national standard benchmarks, offering direct factory quality traceability from raw material fine-grinding to final screening.

As a global B2B tabular alumina supplier, HUAO prepares custom grain size distributions ranging from coarse aggregates to fine powders according to client processing requirements. Standard packaging includes multi-wall 25kg bags, 1000kg/1250kg jumbo bulk sacks, or custom export packaging configured for foreign port handling.
