Fused Mullite is a synthetic material composed of aluminum oxide
(Al2O3) and silicon dioxide (SiO2). It is produced through a
high-temperature fusion process where a mixture of alumina and
silica is heated to around ***0 to ***0 degrees Celsius. The
extreme heat causes the raw materials to melt and react, resulting
in the formation of mullite crystals.
Fused Mullite has excellent thermal stability, high strength, low
thermal expansion, and good chemical resistance. It is known for
its exceptional refractory properties, making it suitable for
various high-temperature applications. Some common uses of fused
mullite include: Refractory Applications, Ceramic Industry, Foundry
Industry, Abrasives, etc.
Fused Mullite is a valuable material in industries where
high-temperature resistance, mechanical strength, and chemical
stability are essential. Its versatility and reliability make it a
preferred choice for demanding applications in the refractory,
ceramic, and foundry sectors.
Refractory Applications: Fused Mullite is widely used in the
production of refractory bricks, castables, and other refractory
products. Its high refractoriness, resistance to thermal shock, and
low thermal conductivity make it ideal for lining kilns, furnaces,
and other high-temperature industrial equipment.
Ceramic Industry: Fused Mullite is used in the manufacturing of
advanced ceramics, such as crucibles, thermocouple protection
tubes, and kiln furniture. Its excellent thermal stability and
resistance to chemical attack make it a preferred material for
ceramic applications.
Foundry Industry: Fused Mullite is utilized in the foundry industry
as a material for molds and cores due to its high-temperature
strength and dimensional stability.
Abrasives: Fused Mullite can be processed into abrasive grains that
are used in grinding wheels, cutting tools, and other abrasive
applications. Its hardness and toughness contribute to its
effectiveness as an abrasive material.
