Composition
Mullite Insulating Refractory Brick is made of aluminum powder,mullite powder,kyanite,
suzhou clay and other high pure raw material.which can minimize the effects of inpurity effectively.Produced by special technology,sintering at high temperature,then boundary cutoff to make precise size.
Features
With features of good thermal shock resistance,stable volume, high service temperature,high cold crushing strength and low thermal conductivity.
Application
As the most perfect lining and insulating material in high temperature furnaces and klins,this product have been widely used in many kinds of furnaces inmetallurgical,mechanical,
ceramic,petrochemical industries.It is a perfect energy-saving product,the maximum service temperature is 1500oC.
