Developed using excellent quality raw materials, these mullites are suitable for casting all type of alloys and metals. Our reputed vendors professionals process the entire assortment of chemicals in accordance with the international quality norms and standards. The offered Fused Mullite are given to the clients in variety of size fractions as per the requirements of our esteemed customers.

Features:

High thermal stability
Low reversible thermal expansion
Resistance to slag attack at high temperatures
Stable chemical composition

Process of Production :

Fused Mullite is produced by Bayer process alumina and high purity quartz sand while fusing in super-large electric arc furnace.

It has a high content of needle-like mullite crystals which confer high melting point, low reversible thermal expansion and excellent resistance to thermal shock, deformation under load, and chemical corrosion at high temperature.

Application :

It is widely used as raw materials for high grade refractories, such as the lining bricks in glass kiln furnace and bricks used in hot wind furnace in steel industry.
It's also used in Ceramic kiln and petrochemical industry and many other applications.
