Fused silica brick, with the same silica brick properties as silica bricks, is also known as zero thermal expansion fused silica brick or thermal shock resistance silica brick. Fused Silica Refractory is an extremely insulating material with very low thermal conductivity and good thermal shock resistance, typically used in flow control/continuous casting applications and glass rolls.
Product Description
Fused Silica Refractory is an extremely insulating material with very low thermal conductivity and good thermal shock resistance, typically used in flow control or continuous casting applications (for steelmaking) and glass rolls.
What Is 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 material is amorphous fused silica. Its thermal expansion coefficient is near zero, so the product is also named zero thermal expansion silica brick.
Silica refractory brick 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.
Fused silica refractory material 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.
Hebei XUANKUN Refractory Material is one of the leading silica bricks manufacturers in China with international production standards. Xuankun Refractory Material has the ability to produce special and customized silica bricks with high quality to meet customers needs. With advanced silica bricks production technology, Xuankun Refractory Material has already sold the silica bricks refractory products to India, Southeast Asia, and even to Africa, Europe and other countries.

Advantages of Fused Silica Brick
1. Longer service life, accurate size tolerance and 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 abilities.
Application of Fused Silica Refractory
Fused Silica Refractory is widely used in hot repair projects on coke oven, glass furnace and hot blast stove. Fused Silica bricks have the characteristics of large volume density and high strength, whose quality is strictly controlled in the production process. The Fused Silica Refractory is no crack and peeling, long service life, safe and reliable after hot repair.
