Mullite bricks are a high aluminum refractory with mullite as the main crystal phase. Generally, the content of alumina is between 65% and 75%. In addition to mullite, the minerals with lower alumina content also contain a small amount of vitreous phase and cristobalite. The higher alumina content also contains a small amount of corundum.
