As we know,the mullite brick are refractory products with synthetic mullite as raw material and mullite as main phase.When the Al2o3 content of mullite brick is lower than the theoretical composition of mullite, there will be a small amount of square-spar; when the Al2o3 content is higher than the theoretical composition of mullite, this series of refractory bricks will contain a small amount of corundum.
Mullite refractory brick is made by high pressure molding and high temperature sintering, which has excellent thermal shock stability, abrasion resistance and chemical erosion resistance.And the mullite brick is widely used in the ignition system of CFB boiler and other industrial kilns.
The mullite refractory brick is widely used in hot air furnace top, blast furnace body and bottom, glass furnace heat storage chamber, ceramic sintering kiln and oil cracking system blind lining.
Mullite refractory brick can be roughly divided into sintered mullite brick and fused mullite brick. Compared with sintered mullite, the crystallization of electrofused mullite is larger and the thermal shock resistance is slightly better than the quality of sintered products. The high temperature performance mainly depends on the content of alumina and the uniformity of mullite phase and glass distribution.
