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.

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.

Fused Mullite

MUB

MUB is a fused mullite obtained from fusion of high purity sand and alumina in an electric arc furnace. It presents low thermal expansion and high thermal shock resistance that make MUB an excellent material for investment casting and other refractory applications.

MUBS

MUBS is a fused mullite obtained from fusion of silica sand and alumina in an electric arc furnace. It is less pure than MUB but also presents low thermal expansion and high thermal shock resistance that make MUBS an excellent material for investment casting and other refractory applications.

MUBW

MUBW is an extremely pure fused mullite obtained from fusion of silica sand and alumina in an electric arc furnace. It presents low iron contamination, low thermal expansion, high thermal shock resistance and high temperature strength. It is an excellent material for investment casting and other refractory applications.
