Sillimanite minerals made of refractory bricks. Sillimanite after calcination into mullite and free silica. Generally high temperature firing method and slurry casting method to produce. Its physical and chemical properties of high-alumina brick well, 1770~1830℃ refractoriness, loading start softening 1500~1650℃. Main fluid cavity molding for glass furnaces, blast furnace, furnace lining and throat, as well as ceramic kiln furniture.

Refractories for glass production is an important guarantee for the glass industry. In recent years, the continuous efforts of engineers and technicians, exploration and development, glass refractories are changing a welcome change, a number of new refractory materials are applied to the glass industry. Book will be applied to the glass industry in the silica, clay texture, high alumina, magnesia, zirconia, fused refractory materials, as well as the composition, properties, classification of unshaped refractory materials, standards, demonstrate. 
For all kinds of production of refractories, refractories, refractory selection and configuration, refractory masonry construction are described.
