Silica Bricks are refractory material primarily composed of silicon dioxide (SiO₂). It features high refractoriness, excellent thermal shock resistance, and a low thermal expansion coefficient. It is widely used in industries such as steel, glass, ceramics, and cement. · High Refractoriness: With a refractoriness exceeding 1690°C, it is suitable for high-temperature environments. · Excellent Thermal Shock Resistance: Capable of withstanding rapid temperature changes, reducing thermal shock damage. · Low Thermal Expansion Coefficient: Maintains dimensional stability under high temperatures. · Strong Resistance to Acidic Slag Erosion: Demonstrates robust resistance to acidic slags.
