Silica brick is a kind of acid refractory mainly made from tridymite, cristobalite and a small amount of residual quartz as well as glass phase. The raw material is natural silica sand whose SiO2 content should be more than 96%. The higher SiO2 content in silica sand, the higher temperature silica bricks resist. Silica bricks are used in the roof and superstructure of glass melting tanks as well as for hot repairs.
