The meaning and charicteristic of Mullite brick

High aluminum refractory material is by mullite (3Al2O3·2SiO2) as the main chip.  Mineral composition in addition to the mullite, Containing the alumina lower also contains a small amount of glass phase

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.
