Description
Corundum Brick
Material System & Positioning
Corundum bricks use fused or high-purity sintered corundum with Al₂O₃ ≥99%, refractoriness ≥2000℃, bulk density ≥3.20 g/cm³ and CCS ≥80 MPa. Chemically pure, high-temperature resistant, resistant to gas and dust erosion with dense high-strength structure. It is Henan Songrui's premium grade for petrochemical gasifiers and high-temperature reactors.
Key Performance
- High-purity corundum: Al₂O₃ ≥99%.
- High temperature: refractoriness ≥2000℃.
- Erosion resistance: withstands gas and dust flow.
- Dense and strong: high hot strength.
Applications
- Petrochemical: gasifier linings, high-temperature reactors, reformers.
- Steel & Iron: ladle slag lines (high-purity option), RH snorkels.
- Glass: tank wall hot sections.
- Ceramics: high-temperature kiln furniture.
Selection Advice
Use for purity- and temperature-critical zones; high-alumina or mullite bricks meet general hot zones at lower cost. Lay with corundum mortar in tight joints.
Installation & Maintenance
Lay with corundum mortar, strict joints; reserve expansion joints in hot load-bearing zones.

FAQs
Al₂O₃ content of corundum brick?
Al₂O₃ typically ≥90% with service up to 1800℃—highly refractory and slag-resistant.
Applications of corundum brick?
Ladle slag lines, hot metal ladles, RH snorkels, gasifiers, glass tank walls.
Corundum brick vs corundum castable?
Bricks offer stable dimensions for regular walls; castables suit irregular shapes and fast repair.
