Description

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 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.

 

2. Silica brick Feature   

  • Silicon oxide is above 95%.
  • Good acid erosion resistance.
  • High softening point with temperature.
  • No shrink in burn repeatedly.
  • Temperature of refractorin
  • ess under load is above 1650º C
