Product Description
Silica insulating bricks are mainly made up of top class silica, and burned under very high temperature. It has the below properties:
1) Silicon oxide is above 95%.
2) High acid-erosion resistance.
3) High softening point
4) Low impurities.
They can be widely used in blast furnace and hot blast stoves...
