Sillimanite Products
Introduction:
Sillimanite, kyanite, andalusite have the same chemical composition but different crystal structures.They are all irreversibly converted to mullite and SiO2 at high temperatures with a volume effect.The sillimanite product is prepared from a sillimanite mineral by high temperature firing or mud casting, and has good characteristics. Its physical and chemical indicators are better than fire clay bricks.
Advantages:
High temperature thermal stability, high refractoriness, resistance to molten glass erosion, low pollution to glass liquid
Application:
For glass industry feeding channel, feeder, pipe drawing machine, such as feeder channel block, spout, bowl, stirrers, plunger, tube, burner block, etc.
