Product Description

 

 

Refractory White Corundum Hollow Ball Fused Alumina Bubble is a new type of high temperature insulation material which is made from industrial aluminum treated by smelting in an electric furnace. The crystal form is a-Al2O3 micro crystals.

Refractory White Corundum Hollow Ball Fused Alumina Bubble can be made into various shpes with the highest temperature 1800 ℃, which is of high mechanical strength, and the volume density is only one-half of corundum products.

 

 

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.

 

 

 

 

 

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.
