A neutral refractory material with an alumina content of over 48%. It is formed and calcined from raw materials with high alumina content, such as bauxite or other materials. The refractoriness of high alumina brick is 1770°C. High alumina bricks are advanced refractory materials made of high-grade bauxite, fused corundum and fused mullite as main raw materials.
High thermal stability
Good slag resistance, acid and alkali resistance
Good thermal conductivity
High temperature strength
Low apparent porosity
