Sillimanite bricks are high-alumina refractory products made from natural sillimanite minerals (sillimanite, andalusite, kyanite) as the main raw materials, and their chemical composition is Al2O2-SiO2 system. The Al2O2 content is usually higher than that of ordinary high-alumina bricks, with a refractoriness of 1770-1830℃ and a load softening temperature range of 1500-1650℃.
