Feature of silica brick :
1.Good thermal stability, low thermal conductivity, good insulation performance.
2. Low bulk density, good integrity, high mechanical strength.
3. Good thermal shock stability, good resistance to abrasion and corrosion.
4. Good volume stability at high temperature.
5. Low water absorption rate, low creeping rate.
6. Natural clay products, could be shaped freely, non-radioactive and environmentally friendly.
