Advantages for Calcium-free Silica Brick

1. Longer service life, accurate size tolerance, pure color

2. Excellent thermal shock resistance, no need to shut down the kiln when hot repairing

3. Good structural strength at high temperature.

4. Zero thermal expansion coefficient, no need for expansion joints,Improve the tightness of masonry.

5. Rare crack and peeling phenomena.

6. No preheating required

7. SiO2content is above 99%.

8. Low flux index (less than 0.3%), no pollution to product.

9. Good anti-erosion and acid-resistance.

Application

It is widely used in hot repair projects on coke ovens, glass furnaces, and hot blast stoves. After hot repair, there are no cracks or peeling, long service life, safe and reliable.
