Fused Zirconia Mullite/FZM
Fused Zirconia Mullite /FZM PROCESS OF PRODUCTION
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.
