Product Description
Introduction:
Fused Alumina Bubble 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.

Grain (mm)0.2-1,0.5-1,1-3,2-3,3-4,5-8

Applications:

Alumina bubble is used in the production of lightweight insulating refractories where low thermal conductivity, and high temperature properties are the prime requirements. It is also used effectively for loose-fill refractories.
