Description For Silica Brick Silica brick is made of quartz stone material, the content of SiO2 is above 93%. It has good resistance to acid slag and good heat conductivity. And the refractoriness is 1690~1710°C,long-term use volume at high temperature is relatively stable. 
Stable Capability, High Quality, Excellent Service, Competitive price is the most important advantage of our products.
 
Silica Brick Advantage
1. Excellent chemical attack resistance, slag resistance and acid resistance; 2. No pollution to products (such as molten glass, etc.); The main component of silicon brick is SiO2, and if there are blocks or surface droplets during use, the quality of molten glass will not be affected. 3. Excellent thermal stability, the product will not explode during hot repair, and the repair operation can be carried out directly; 4. High temperature volume stability, no shrink in burn repeatedly. 5. Small bulk density. The mass of the furnace can be reduced. 6. After repair (hot repair), there will be no peeling and other phenomena, and it is safe and reliable for long-term use;

Lightweight Silicon Insulation Brick

 
1. Silicon oxide is above 95%. 2. Good acid erosion resistance. 3. High softening point with temperature. 4. No shrink in burn repeatedly. 5. Temperature of refractoriness under load is above 1650º C.

Product Application

Refractory Silica Brick Application Silica bricks are mainly used for the partition walls of the carbonization chamber and combustion chamber of coke ovens, the regenerative chamber of steel making open hearth furnaces, soaking pits, refractory materials of glass furnaces, Tunnel kilns, rotary kilns, metallurgical furnaces,and ceramic firing kilns, as well as other load-bearing parts of kilns. It is also used for high-temperature load-bearing parts of hot air furnaces and acidic open hearth furnaces. Silica bricks are also widely used in construction and equipment in chemical, petroleum, pharmaceutical and other industries.
