Fused Mullite is produced by Electro fusing Calcined alumina and high purity quartz sand in an 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 temperatures.
