Prodcut Name:Fused Mullite

Product Description

Fused Mullite is produced by the electric furnace fusion of alumina and high purity silica. The fused mullite has low conductivity, excellent thermal shock resistance, and excellent resistance to deformation under load. It is used in applications such as refractories for glass and steel industries, as kiln furniture, in investment casting as shell building materials, in spark plug bodies, and many other applications.
