- Parameters
Aluminabubble brick use the hollowalumina sphere(bubble alumina), corundum powder, calcined powder as rawmaterial, through Homogenization, molding, high temperature sintering. Hightemperature resistance, low thermal conductivity, good thermal insulation, goodchemical stability (acid- base erosion resistance), low bulk density (lighterthan the same kind of material, thin kiln wall, low cost).
Widely used in inner linings of variousnon contacted melt high temperature kiln and thermal insulating layers of hightemperature kilns.
