Fused Zirconia Mullite is Manufactured from high quality Bayer process alumina and zircon sand in electric arc furnace, During melting, the zircon and alumina react to yield a mixture of mullite and zirconia.
Fused Zirconia Mullite is composed of large needle-like mullite crystals containing co-precipitated monoclinic ZrO2.
Fused Zirconia Mullite APPLICATION
Fused Zirconia Mullite 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.
