High Alumina Poly Lightweight Insulating Bricks

High alumina poly lightweight insulating bricks are typically manufactured by blending high-grade bauxite chamotte with a small amount of clay, followed by fine grinding. The slurry is then cast into shape using gas generation or foaming methods, and fired at temperatures ranging from 1,300C to 1,500C.
