Bubble Alumina

Bubble Alumina (alumina bubble) is produced by high purity industry alumina in electric arc furnace products. The product chemistry is similar to that of white fused alumina. Alumina bubbles are formed from α-alumina, resulting in hollow spheres of low bulk density and high insulating property. At high temperatures, they have good chemical stability and corrosion resistance.
