Slilica mullite fire brick is mainly made of mullite as the main material and contain over 30percent SiO2 content and over 60 percent Al2O3 content. slilica mullite firebrick refractoriness generally is more than 1580 degree. silicate mullite fire brick is composed mainly of mullite, corundum, SiC and glass. refractory silicon mullite brick is formed at the junction of granules as mullite, glass and SiC. silicate mullite firebrick with high quality and various excellent properties for application in all kinds of high temperature furnace and kilns, such as roasting furnace.
Silicon mullite block is made with raw material high grade bauxite and SiC and special sintering process. Silica mullite bricks are characterized by high density, good performance of abrasion resistance and thermal shock resistance. silicate mullite block can constantly form protective layer for reducing accrection formation, long application cycle.
