Fused Silica Brick

Product Description

What's Fused Silica Refractory Brick

Fused silica brick is also known as zero thermal expansion fused silica brick or thermal shock resistance silica brick. The main raw materials are amorphous fused silica. It's thermal expansion coefficient is near zero, so the product is also named zero thermal expansion silica brick.

Zero expansion silica bricks is High thermal shock resistance and zero expansion silica bricks produced with fused silica as the main raw material, with resistance to thermal shock when warming up, high strength, low expansion rate, acid erosion resistance and many other advantages, it is the best choice for glass kiln as hot patching bricks.

It is widely used in hot repair project on coke oven, glass furnace and hot blast stove. After hot repair, no crack and peeling, long service life, safe and reliable.

Advantages for Fused 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 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 than0.3%), no pollution to product.

9. Good anti-erosion and acid-resistance.

Application for Zero-expansion Silica Brick

It is widely used in hot repair project on coke oven, glass furnace and hot blast stove. After hot repair, no crack and peeling, long service life, safe and reliable.
