Product Details

Silica brick is made of silicon as raw material with high temp firing ,which silicon oxide is above93% ,used in hot blast furnace,coke oven,glass kiln,these brick have good volume stability at high temperature,  high refractoriness under the load,small rate of shrinkage in working condition.


Features Of Silica Brick

  • Lower impurity content

  • Excellent resistance in slag abrasion

  • No shrink in burn repeatedly

  • Super higher cold crush strength character

  • Good performance in high temp refractoriness under load
