Fused Mullite

 

 

Process Of Production:

 

 

 

 

Fused Mullite is produced by Bayer process alumina and high purity quartz sand while fusing in super-large electric arc furnace.

 

It has a high content of needle-like mullite crystals which confer high melting point ,low reversible thermal expansion and excellent resistance to thermal shock ,deformation under load, and chemical corrosion at high temperature.
