Introduction of silica brick:
Silica brick is made of quartz stone material, the content of SiO2 is above 96%,it has good resistance to acid slag and good heat conductivity. And the refractoriness is 1690~1710°C,RUL is beyond 1680°C.
SiO2 has different types of crystals in different temperatures, and the transform between the crystals will cause the change of the bulk. So there is a close contact between the changes of SiO2 crystals and the produce ,performance and usage of silica bricks. During the heating, there will be changes of the bulk ,and cristobalite changes most, then quartz, phosphorus quartz is the slowest of all and it also has good heat-conductivity.Coke oven should use the silica brick with small true density. And the phosphorus quartz is better than others.
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.

Advantage of silica brick :
1.Silicon oxide is above 96%.
2.Good acid erosion resistance.
3. High softening point with temperature.
4. No shrink in burn repeatedly.
5.Temperature of refractoriness under load is above 1680º C
Application of silica brick :
1.Widely used in coke ovens.
2.Used in high temperature sections of the checker chamber in hot blast stoves.
3.Used as low-cost alternative to andalusite and mullite checker bricks in hot blast stoves.
4.High refractoriness, average thermal shock resistance make it suitable in consistant temperature environment.
