Silimanite brick:
Sillimanite brick is a high-grade refractory material, which has the characteristics of low thermal expansion rate, good resistance to metallurgical slag and to corrosion of various glass liquids, and high temperature wear resistance. Sillimanite refractory bricks have the Refractoriness of 1770 ~ 1830 ℃, load softening starting point 1500 ~ 1650 ℃. Sillimanite bricks are widely used in feeder channels, feeder covers, burners, melting bottom paving of glass furnaces and other applications.
