Product Description

 

 

Fused Bubble Alumina is produced by blowing the melt of high purity Bayer process alumina in a controlled atmosphere to produce hollow spheres. Due to its low density and extremely low thermal conductivity fused alumina bubble is ideal for high alumina based Insulating Bricks and castables.

 

 


Its main raw material is high quality alumina powder. After melting through the electric arc furnace, blowing and then instantaneously cooling in air, the alumina bubble will have the characteristics of light weight, closed hole and high temperature resistance. It is the ideal heat-insulated filler for high temperature furnaces, as well as the high quality aggregate for high temperature light refractory castable.
Alumina bubble as the main material can be made into various shapes of products, with the service temperature 1800 ℃. The finished products have the high mechanical strength, which is several times higher than general light products, while its bulk density is the half of corundum products

 

 

 

 

 

Application:
 
 
At present the alumina bubble is mainly used in the high temperature furnace / industrial furnace insulation, such as petrochemical industrial gasifier, carbon black industrial reactors, metallurgical industrial induction furnace and other high temperature, ultra-high temperature furnace. The energy saving effect is very good.
