At present, there are many kinds of refractory bricks, such as mullite bricks, high alumina bricks, insulating bricks, magnesia bricks and so on. The mullite bricks are high alumina refractories with mullite as main crystal phase. Alumina content generally between 65% ~ 75%. In addition to mullite mineral composition, the lower of which contains alumina also contains a small amount of glass phase and cristobalite, while the high alumina containing a small amount of corundum, a higher degree of fire resistance, up to 1790 ℃ or more. For more information about mullite bricks nature, purpose, price, welcome you at any time to pay attention to Rongsheng Refractory website, you are welcome to inquire,to buy.
