Fused silica brick is a high-purity, corrosion-resistant refractory brick, mainly used for the upper wall part of the furnace, especially suitable for the construction of low-alkali borosilicate glass. Manufactured at the Sunrise facility, the product offers significant advantages, including high purity, small thermal expansion coefficient and good thermal shock stability. During use, fused silica bricks exhibit high viscosity and strength at high temperatures, and have strong slag resistance and impact resistance. In addition, its low thermal conductivity and small drying and firing shrinkage make it excellent in high-temperature environments.
