Bubble Alumina is made of high Al2O3 purity fused alumina. The hollow bubble shape gets from the blowing process after fusing. The main crystal structure of bubble alumina is α-Al2O3. With a good control system, the ball shape rate from us is up to 90%. It is a kind of light refractory material with excellent high-temperature resistance and energy saving.

 Application:

— Pore making material of diamond wheel to avoid the burning of the grinding wheel

— Lightweight aggregates of high refractory concrete

— Refractory bricks & insulation fire bricks

— Kiln future material, high-temperature furnace lining material
