Audited Supplier Product Description Of JM23 JM26 JM28 JM30 Insulation Refractory Brick
Mullite brick is a high-alumina refractory with mullite (3Al2O3·2SiO2) as the main crystal phase. Generally, the alumina content is between 65% and 75%. In addition to mullite, the mineral composition contains a small amount of vitreous phase and cristobalite with a lower alumina content; a small amount of corundum is also contained in the higher alumina content.
Mullite refractory bricks have high refractoriness, which can reach above 1790ºC. The starting temperature of softening under load is 1600~1700ºC. The compressive strength at room temperature is 70~260MPa. Good thermal shock resistance. There are two types of sintered mullite bricks and fused mullite bricks. Sintered mullite brick is made of high alumina bauxite clinker as the main raw material, adding a small amount of clay or raw bauxite as a binder, and is made by molding and firing. Fused mullite bricks use high bauxite, industrial alumina and refractory clay as raw materials, add charcoal or coke fine particles as reducing agents, and use reduction electrofusion method to manufacture after molding. The crystallinity of fused mullite is larger than that of sintered mullite, and its thermal shock resistance is better than that of sintered products. Their high temperature performance is mainly determined by the alumina content and the homogeneity of the mullite phase and glass distribution
