Mullite poly brick is also known as light mullite brick or mullite thermal insulation brick, mullite thermal insulation brick is made of high quality bauxite clinker as the main raw material, plus an appropriate amount of clay, ingredients and water mixed to make plastic mud or mud, extrusion molding after high temperature fired high-quality thermal insulation brick.
Mullite insulation brick is mullite (3Al2O3·2SiO2) as the main crystalline phase of high alumina refractory, the general alumina content between 40% and 75%, mineral composition in addition to mullite, which contains low alumina also contains a small amount of glass phase and cristobalite, containing high alumina also contains a small amount of corundum.
