Bubble Alumina 
1.Used to make Refractory 
2.Excellent quality makes your Kiln running well 
3.Professional Producer

Bubble Alumina is an electric arc furnace product made from high purity Bayer process alumina and the product chemistry is similar to that of white aluminum oxide. Bubbles are formed from molten alumina, resulting in hollow spheres of low bulk density.

Application:

Bubble Alumina 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
