Mullite insulation bricks are made from good quality and superpure
raw materials, with strictly classified fillings
according to their grades. These fillings can form a uniform pore
structure after burnt during the process of
manufacture. Each grade of products has unique design to meet
different thermal, physical and chemical demands.
Mullite insulation bricks refractory material can be used in
linings or heat-insulating materials of the industries,
such as, ethylene pyrolysis furnaces, tubular furnaces, reforming
furnaces of synthetic ammonia, gas generators and high-temperature
shullte kilns, etc.
