Product Description

High Quality Stove Sintered Silica Refractory Brick 92% Sio2 Silica Brick for Coke Oven

Product Description

Refractory Silica Brick Description

Silica brick is made of quartz stone material, the content of SiO2 is above 93%, it has good resistance to acid slag and good heat conductivity. And the refractoriness is 1690~1710°C,RUL is beyond 1620°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.

Advantages of Silica Fire Brick:

1) Silicon oxide is above 95%.
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 1650º C.
6) Stable Capability, High Quality, Excellent Service, Competitive price is the most important advantage of our products.
