Bauxite based sintered mullite
Sintered Mullite is made of high-quality bauxite, by multistage homogenization and sintering above 1750 ° C. It has the characteristics of high density, stable quality, good thermal shock stability, small high temperature creep value and good chemical corrosion resistance. It is an ideal raw material for the production of various shaped and unshaped refractory materials, high-grade sanitary ware embryo, precision casting model and other refractory products.
