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.

 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. Low bulk density, low thermal conductivity, good thermal insulation performance.

2. Refractory category allow direct contact of fire, suitable offer various atmosphere

3. Good integrity with furnace lining, long service life, easy operation, could be shaped freely

4. Can be used in various kilns because of its cheapness and general tray package.
