Introduction

Sintered mullite brick is made of chamotte as raw material, use clay or bauxite as binder, after mixing, shaping, drying, sintering at high temperature in kiln, the whole process is finished.

Application

Primarily used for middle and under parts of regenerator of glass furnace, also can be used as checker brick. Sintered mullite brick is widely used in roof, furnace shaft and bottom of hot blast furnace and lining brick of ceramic sintered kiln.
