Silica Refractory Brick Features 1. Excellent refractoriness under load: Silica bricks can reach a temperature as high as 1640-1680°C. 2. High high-temperature strength: At high temperatures, the strength of silica bricks increases with increasing temperature. 3. Strong resistance to acidic slag erosion: As an acidic refractory material, silica bricks offer excellent resistance to acidic slag (such as FeO and SiO₂). 4. Excellent structural stability: The high refractoriness under load and high-temperature strength of silica bricks ensure the long-term stable operation of the kiln structure. 5. Long service life: Silica bricks' corrosion resistance and high-temperature stability ensure a long service life. 6. Excellent thermal insulation: Their low bulk density provides a certain degree of thermal insulation. 7. High cost-effectiveness: For certain large-scale industrial kilns, silica bricks are a key and economical choice for long-term, stable, and efficient operation.
