White Corundum Bricks: High‑Purity Sintered Refractory for Extreme‑Temperature Industrial Kilns

TY Refractory’s premium White Corundum Bricks are sintered from high‑purity corundum aggregates with Al₂O₃ content above 90%. This high‑grade neutral refractory features high working temperature, reliable thermal stability, superior cold crushing strength and excellent resistance against acid‑alkali chemical corrosion for harsh high‑temperature industrial furnace operating zones.

This dense brick delivers stable core technical performance: bulk density ≥3.0 g/cm³, apparent porosity ≤18%, cold crushing strength ≥100 MPa, and long‑term service capability above 1700°C. Its low‑impurity homogeneous matrix restricts slag and molten medium infiltration. It resists mechanical abrasion and thermal cycling stress, retaining complete structural integrity under continuous heavy‑duty production conditions.

The versatile White Corundum Bricks apply to metallurgical furnace slide rails, walking‑hearth‑furnace tapping troughs, waste incinerator linings, petrochemical kilns, glass furnaces and non‑ferrous smelting equipment. Custom‑shaped bricks can be manufactured strictly per‑customer drawings for special lining layouts.

Backed by over 20‑year refractory manufacturing experience, our factory holds complete ISO triple‑system certifications and 21 proprietary technical patents. Rigorous batch‑wise laboratory testing guarantees consistent quality. Global industrial plant operators select our White Corundum Bricks to extend kiln campaign cycles and cut recurring maintenance expenses.
