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.

Contains high chemical purity with Al₂O₃ ≥ 99.2%, low silica (≤ 0.09%), and low iron (≤ 0.02%) to prevent low-melting glass phase degradation at high temperatures.
Bulk density ≥ 3.50 g/cm³ and porosity ≤ 5.0% enhance physical durability and slag infiltration resistance.
Water absorption maintained at ≤ 1.5% significantly lowers water mixing requirements in castables and reduces binder addition in shaped refractories.
Uniform grain shapes with minimal flake particles improve interstitial aggregate packing and enhance castable workability.
High structural toughness and chemical stability minimize spalling and thermal shock damage caused by operational temperature swings.
| |
Used as the principal aggregate in functional refractory shapes such as sliding gate valves, purging plug cores, ladle shrouds, and continuous casting components where high thermal shock stability and molten steel scour resistance are required.
Serves as an essential high-alumina constituent in refractory castables, gunning mixes, and ramming mixes for induction furnaces and steel ladles, helping improve lining lifespan.
Applied in petrochemical gasifiers, secondary reformers, ceramic kiln furniture, and severe high-temperature processing zones requiring volume stability and corrosion resistance.
