Manufactured from pure quartz sand and industrial alumina in super-large electric arc furnace, it has a high content of mullite crystals which confer high melting point ,excellent thermal stability ,low reversible thermal expansion and resistance to thermal shock and chemical corrosion at high temperature .It is widely as lining bricks in glass body kiln and large hot wind furnace in iron-making blast furnace ,as well as in ceramic kiln and petrochemistry .
Fused Mullite is produced by the electric furnace fusion of high purity alumina and high purity silica. Fused Mullite is a needle-like alumina-silica grain that has great features like:
● Low conductivity
● Excellent thermal shock resistance
● 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
