Silminite Bricks
Sillimanite bricks are based on sillimanite raw materials and a bond matrix made of reactive alumina, refractory clays and ultra fine sillimanite.
The range of products include bricks with different Al2O3 content, low iron products with excellent CO resistance and the phosphate bonded quality with improved slag resistance.
Applications in the steel and non-ferrous metals industry in direct contact with liquid metal are possible. Our sillimanite bricks are very good for refractory solutions in the glass industry, cement industry and incineration, for industrial processes with rapid thermal shocks, in furnaces for firing biomass and in production kilns of the ceramic and refractory industry.
