Fused Zirconia Mullite
Process Of Production:
FZM 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.
It is composed of large needle-like mullite crystals containing co-precipitated monoclinic ZrO2.
Our fused mullite is produced by the electric furnace fusion of Bayer process alumina and high purity silica. The result is a needle-like alumina-silica grain that has low conductivity, excellent thermal shock resistance, and excellent resistance to deformation under load. Fused Mullite is used in applications such as refractories for glass and steel industries, as kiln furniture, in investment casting as shell building materials, in spark plug bodies, and many other applications.
