Made from the natural high-quality bauxite, our product is through multi-level homogenization, and then calcined at over 1750° C. It possesses many good characteristics such as high bulk density, stable quality, good thermal shock resistance, small index of high temperature creep and good resistance to chemical corrosion. It is an ideal raw material for the following refractory products like a variety of shaped and unshaped refractories, advanced ceramic sanitary ware body, precision casting models and so on.
