Product Overview

Leadsun high alumina bricks are made from high-quality bauxite chamotte under advanced production techniques and strict quality inspection. With corundum and mullite as the main mineral phases, the bricks offer outstanding high-temperature strength, excellent chemical corrosion resistance, and long service life.

Key Advantages
  • Excellent high-temperature resistance for continuous industrial use
  • High alumina content ensures superior refractoriness and thermal stability
  • High bulk density and low porosity for enhanced strength and durability
  • Outstanding resistance to slag, erosion, and chemical corrosion
  • Stable performance under severe thermal shock conditions
  • Long service life, reducing furnace downtime and maintenance costs
  • Suitable for steel, cement, glass, and metallurgical furnaces
  • Cost-effective refractory solution with consistent quality
