Fused Mullite is a kind of artificially produced fused product with acicular crystals, which has good thermal resistance, strong modulus of rupture, high refractoriness under load (RUL), high hardness, and good high-temperature creep-resistance.

Fused Mullite is widely used in manufacturing many refractory products, like the low creeprupture bricks for the hotair stove, meltingiron groove or torpedo car, high temperatureindustrial kiln, glass melting furnace, as well as in producing high temperature saggers or shed planks, etc.
