Light weight fire clay insulation brick is made of fire clay materials and the content of alumina in it is 35%-48%. It is manufactured by grinding and mixing the crushed combined clay and levigated clinker, confecting with particle clinker into medium dry pug, high pressure molding, and firing under the temperature of 1200℃-1400℃.
