High Alumina Insulation Brickcsrefractory
High alumina insulation brick refers to all lightweight bricks with AL2O3 more than 45 . It is made of bauxite and a small amount of clay. After grinding it is poured into a slurry form by gas or foam. It burns at a temperature of 1300 1500°C. This kind of brick is not directly exposed to the high temperature in the kiln but only has a thermal insulation layer near the kiln wall.
