Fused Mullite
Fused mullite is an acicular crystal made of manufactured alumina and quartz sand.
Description
Due to its good thermal shock resistance, high rupture strength, high refractoriness under load, high hardness, minor change under high temperature, etc., the fused mullite is widely used in ladle, torpedo ladle brick, high-temperature industrial kiln brick, glass kiln lining brick and high-temperature sagger, slab and other refractory products.
