Zero-expansion Silica Brick

1. Content of SiO2 is greater than 99%, with excellent corrosion resistance and acid resistance  2. Content of Fe2O3 is less than 0.1%, without contamination of products (such as glass melt, etc.)  3. Melt index (Al2O3 + 2R2O) is less than 0.3%  4. The coefficient of thermal expansion is close to zero, and no expansion seams may be reserved during repair to increase the tightness of masonry  5. Excellent thermal stability allows the product not to crack during hot repair, and be repaired directly under high temperatures without stopping the furnace  6. After repair (thermal repair), flaking and other phenomena will not occur, and long-term use is safe and reliable

Calcium-free Silica Brick

The calcium-free silica brick DES-99 is a new product independently developed by our R&D team. With the adoptaton of the calcium-free sintering technology, the product has excellent chemical stability, and its physical and chemical properties are superior to similar imported products, and thus can replace the equivalent imported products.
