Bubble Alumina

Sizes Available:
0.2-0.5mm, 0.2-1mm,1-3mm,3-5mm,
Other sizes are also available on request.

Bubble Alumina is hollow spheres, It has low bulk density and extremely low thermal
Bubble alumina is used in the production of lightweight insulating refractories, where low
thermal conductivity, and high temperature properties are the prime requirements.
Bubble alumina is also used effectively for loose-fill refractories.
