Product Description
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 (needlelike) 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, refractories,
and other applications requiring a high purity raw material
with excellent thermal shock resistance and hot strength,
like metallurgy, ceramics, constructions, chemicals,
electricity and foundry.
White Fused Mullite, is a first quality refractory
material, composed of massive crystals of mullite which are
formed during cooling after fusion. It confers high melting
point, excellent thermal stability, low reversible thermal
expansion, low porosity, high resistance to thermal shock
and chemical corrosion at
high temperatures.
