and cristobalite, Containing alumina higher contains a small amount of corundum.



High refractoriness, can reach more than 1790 ℃. The rul start temperature is 1600 ~ 1700 ℃. Room temperature compressive strength is 70 ~ 260 mpa. Thermal shock resistance is good. It contains

 sintered mullite brick and fused mullite brick. Sintered mullite brick with high bauxite clinker as the main raw material, add a small amount of clay or raw bauxite as binder, forming, sintering and made.
