Silica Bricks for Modern Coke Oven Batteries

By  F. Brunk  –  Germany

Adopting high quality raw materials and advanced technology, the silica bricks used for coke ovens construction achieve the advantages of high purity, long service life, good thermal conductivity, high refractoriness under load, and good creep resistance.
Silica brick are mainly made from tridymite, cristobalite and a small amount of residual quartz. The raw material is natural silica sand whose SiO2 content should be more than 95%. The mineralogical composition has great influence in thermo-mecchanical properties as requested in German Standard DIN 1089-1 (1995).
