Description

1,Product description:

Sillimanite is a natural high-grade refractory mineral with low thermal expansion rate, resistance to corrosion of metallurgical slag and various glass liquids, and good high temperature wear resistance.

Using natural sillimanite as raw material and fused mullite as secondary material, the compact sillimanite brick produced has good thermal shock stability at high temperature, erosion resistance and high temperature stability, and is widely used in glass tank kiln and blast furnace lining.
