The sillimanite brick is made of sillimanite minerals.After high temperature calcination,it become mullite and dissociate silicon dioxide. Generally use high-temperature firing method and slurry casting method to produce.

Advantage:
Our Sillimanite Brick: with high refractoriness, low creep and mechanical behavior under high temperature, high refractoriness under the load, good thermal shock resistance and slag resistance

1.Good thermal stability.
2.Strong resistance to chemical attack.
3.It is the first choice of stable material for glass forming.
