DESCRIPTION
Fused Mullite is made of high purity alumina and silica sand fused in electric arc furnaces at high temperature. The result is needle-like crystal grains form and has great features as following:
Good characteristics:
Low thermal expansion
Good chemical stability
Excellent thermo-mechanical stability
Excellent thermal shock and corrosion resistance
Low porosity
Comparatively lightweight
Oxidation resistance
Resistance to slag attack at high temperatures
