High alumina insulating bricks are made of selected high alumina bauxite, kaolin clay, and hollow microsphere, high alumina insulation bricks are produced by shaping at high pressure and sintering at high temperature. Lightweight high alumina brick has the characteristics of low bulk density, maximum service temperature is 1350C, high cold crushing strength, low thermal conductivity. High alumina insulation brick can be used in furnace lining and insulation layers, ceramic tunnel kiln, heating furnace and coking furnace in iron and steel industry.
