Fused Zirconia 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 (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
zirconia-mullite is composed of large needle-like mullite crystals containing co-precipitated monoclinic ZrO2
Application:
It is used in specialty product applications where a high resistance to environmental corrosion and a low coefficient of thermal expansion are desirable properties.
Applications include ceramic pressure casting tubes and refractory shapes requiring resistance to molten slag and molten glass.
Zir-mull bricks and bricks used in the Glass Industry as well as an additive in Continuous casting refractories.
