High-strength alkali-resistant bricks

High-strength alkali-resistant bricks are made from low-alumina refractory clay. High temperature crystalline phases in their microstructure increase the chemical corrosion resistance and reduce the penetration and deposition of alkaline volatiles and detrimental components. It is used in preheating zones of CRK.
Composition:Al₂O₃ 25-35%
Available industries:cement industry
Features: excellent chemical corrosion resistance excellent thermal shock resistance



  • Excellent chemical corrosion resistance
  • Excellent thermal shock resistance
  • High strength
  • Stable volume
