Sintered Mullite is produced at over 1750 ℃ high temperature after multiple selection process and multistage homogenization, with the quality natural bauxite as the raw material.
It is characterized by high content, large bulk density, good thermal shock stability, low high-temperature creep value and good chemical corrosion resistance. With the good quality stability, the mullite is the ideal raw material in manufacturing various shaped and unshaped refractories, advanced sanitary ware bodies, crucibles, saggars, precision casting and other products.
