Large Sillimanite Bricks for Glass Kilns are Corrosion-Resistant
Sillimanite bricks for glass kilns are refractory bricks made of sillimanite minerals. Sillimanite is converted into mullite and free silica after high-temperature calcination. Generally, it is produced by the high-temperature firing method and mud casting method. Its physical and chemical properties are better than high alumina bricks, with a refractoriness of 1770~1830℃ and a softening … Read more
