A Brief Understanding of the Mullite Based Products is given below :-

Mullite (3Al2O3-2Si02 or Al6Si2O13 ) is a compound of aluminum, silicon and oxygen. Mullite can also be viewed as a phase in the alumina-silica binary system. Mullite is a synthetic, fused or calcined crystalline aluminum silicate produced in electric arc furnaces from alumina and silica. Mullite usually has an off-white or tan color. Depending on the purity and density, mullite can have superior dielectric and thermal shock properties and resistance to slag and silicate refractory bonds. Mullite is used for refractory tubes, industrial crucibles, analytical labware, dielectric substrates, wear components, and in refractory cements. Refractory grade mullite or alumina-mullite mixtures are commonly produced by calcining Kyanite minerals.
