Our natural SINTERED MULLITE made from The natural high-quality Bauxite, be processed through multi-level homogenization and calcined over 1750degree. It is of high bulk density, stable quality, good thermal shock resistance, small index of high temperature creep and excellent chemical-resistance. It is ideal raw material for refractory products such as different shaped and unshaped refractory materials, advanced ceramic sanitary ware body, precision casting models and so on.
