Advantages for Calcium-free Silica Brick

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

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

3. Good structural strength in high temperature.

4. Zero thermal expansion coefficient, no need for expansion joint, improve the tightness of masonry.

5. Rare crack and peeling phenomena.

6. No preheating required

7. SiO2 content 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, no cracks or peeling, long service life, safe and reliable.
