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