1. Natural Sintered Mullite Introduction
Natural Sintered Mullite is made from the natural high quality bauxite and Sintered Mullite is processed through multilevel homogenization and calcined over 1750C. Natural Sintered Mullite is of high bulk density, stable quality, good thermal shock resistance, small index of high temperature creep and excellent chemicalresistance. Natural Sintered Mullite 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.
