Description of Sillimanite Brick:
With low thermal expansion rate, sillimanite brick not only have good resistance to metallurgical slag and various glass liquids, good wear resistance at high temperature. But also have good thermal stability at high temperature, less pollution to molten glass and high refractoriness under load.
