Fused mullite

Fused mullite

Fused Mullite is produced by fusing high purity alumina and silica together in an electric arc furnace in the proper ratios. The resulting product is characterized by its dendritic (needle-like) shape and unique thermal properties. Fused Mullite has a low coefficient of thermal expansion which results in a product with excellent thermal shock resistance and resistance to deformation under load.

 

Application

Fused Mullite is used for many applications including investment cast shell building, kiln furniture, glass contact refractories, and other applications requiring a high purity raw material with excellent thermal shock resistance and hot strength.
