Product Features：Hollow alumina sphere bricks use the hollow alumina sphere, corundum powder, calcined powder as raw material, through Homogenization, molding, high temperature sintering.
Product Details
Characteristics：Hollow alumina sphere bricks use the hollow alumina sphere(bubble alumina), corundum powder, calcined powder as raw material, through Homogenization, molding, high temperature sintering. High temperature resistance, low thermal conductivity, good thermal insulation, good chemical stability (acid-base erosion resistance), low bulk density (lighter than the same kind of material, thin kiln wall, low cost).
Application：Widely used in inner linings of various non-contacted melt high temperature kiln and thermal insulating layers of high temperature kilns.
