Silica brick is a type of acid refractory. Due to its advantages such as good volume stability and good creep resistance, it is used in the high-temperature parts of hot blast stove.
- Good volume stability and creep resistance at high temperature under load.
- Good thermal shock resistance above 600℃.
- Better corrosion resistance than fire clay brick and common high alumina brick.
- High thermal conductivity.
The silica brick can be widely used in coke oven, hot blast furnace, glass furnace and carbon furnace.
