Alumina Bubble Brick

CUNSE alumina bubble brick is made of alumina hollow ball as raw material, high-performance powder as additive, and organic material as the temporary binding agent, after mixing, drying, forming, firing at high temperature in shuttle kiln, the whole process is finished.

The quality of alumina bubble brick has reached or exceeded the level of similar products at home and abroad.

1. Excellent thermal shock resistance, low thermal conductivity and good performance of insulation.
2. High temperature resistance as Al2O3 content is≥85%.
3. Reduce furnace weight as there are amount of closed pores in alumina bubble brick.
4. Strong ability to resist erosion of gas and slag.
5. Direct contact with flame.

It is suitable for linings of heating furnace.
