Spalling resistant high alumina bricks

Spalling resistant high alumina bricks contain the component that have much smaller expansion coefficient than high-alumina bauxite. The thermal shock stability enhances the high temperature and chemical corrosion resistance.
Composition:Al₂O₃ ≥70%
Bulk Density:≥2.55 g/cm³
Available industries:cement, nonferrous and chemical industry
Features: flexibility corrosion high temperature stability enhance



  • high temperature stability enhance
  • flexibility corrosion
  • excellent thermal shock resistance
  • refractoiness under load high
