Its main raw material is high quality alumina powder. After melting through the electric arc furnace, blowing and then instantaneously cooling in air, the alumina bubble will have the characteristics of light weight, closed hole and high temperature resistance. It is the ideal heat-insulated filler for high temperature furnaces, as well as the high quality aggregate for high temperature light refractory castable.
Alumina bubble as the main material can be made into various shapes of products, with the service temperature 1800 ℃. The finished products have the high mechanical strength, which is several times higher than general light products, while its bulk density is the half of corundum products
