Alumina Bubble Bricks Advantages

Alumina Bubble Bricks adopt alumina bubble ball as the main raw materials, high-performance ultrafine powder as the annexing agent and organic substance as the binding agent through molding and drying, and then are fired in the high temperature shuttle kiln.

  • Light weight
  • High temperature resistance
  • Low reheating linear change
  • Good thermal shock resistance
  • Lower construction cost
  • Saving energy
