Silica brick is  the acid refractory ,which consist mainly of tridymite, cristobalite, and a small amount of residual quartz and glass phases.

The silica content is 94% or more. It has acid slag corrosion resistance and higher high temperature strength. The load softening start temperature is 1620~1670 °C. Long-term use at high temperatures does not deform. The thermal shock stability is low (heat exchange in water for 1~4 times). This residual expansion will make the joints tight and ensure good air tightness and structural strength of the masonry.
