Loading Port:China Main Port

Payment Terms:TT OR LC

Min Order Qty:-

Supply Capability:-

1.Resistance to corrosion and erosion;
2.Least contamination for molten glass;
3.Improve the productivityaa
4.Long life

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.

Applications:

1.Widely used in glass furnace,such as regenerator arch.

2.Mainly used in the blast furnace.
