1. Silica brick Description

Silica brick is made of quartz stone material, SiO2 content is more than 93%, it has acid slag corrosion resistance and high-temperature strength. The load softening start temperature is 1620~1670°C. Silica bricks will not deform after long-term use at high temperatures and have low thermal shock stability. This residual expansion will tighten the joints and ensure that the masonry has good airtightness and structural strength.
