Anti desquamate high aluminum brick is based on high-class bauxite and clinker with ZrO2 synthesis material,with a certain ratio by high-pressure forming a firing products. This kind products is of strong anti-off, but also anti-potassium, sodium, sulfur, chlorine alkali and salt erosion, low thermal conductivity, is an ideal material of transitional and the decomposition zone of cement kiln, it can be used in the cover of kiln door, cooler and other parts.
