Refractory Bricks Manufacturer

Mullite Bricks are high-aluminum refractory materials with mullite (3Al2O3 · 2SiO2) as the main crystal phase. Generally the alumina content is between 65% and 75%. In addition to mullite, those with lower alumina also contain a small amount of glass phase and cristobalite; those with higher alumina also contain a small amount of corundum. Contact RS .  Mullite brick  has a high fire resistance, which can reach above 1790 ° C. Load softening start temperature is 1600 ~ 1700 ℃ . The compressive strength at room temperature is 70 ～ 260MPa. Good thermal shock resistance. Mullite Brick for Sale in RS Refractory Manufacturer Classification of Mullite Bricks There are two types of mullite bricks, one is sintered mullite bricks and another is fused mullite bricks. The sintered mullite brick is made of high alumina bauxite clinker, and a small amount of clay or raw alumina is added as a binder, and then formed and fired. The fused mullite brick is made of high alu...
