Product Description of Lightweight Silica Insulation Bricks For Superior Thermal Insulation in High-Temperature Environments
Our refractory Silica Insulation Bricks are an acid refractory material primarily comprised of flake quartz, crystalline quartz, and small amounts of residual quartz and glass phase. They demonstrate outstanding resistance to erosion from acidic slag and possess a high load softening temperature ranging from 1640 to 1670°C. Additionally, they exhibit minimal volume change during prolonged exposure to elevated temperatures.
Our Lightweight Silica Bricks are meticulously crafted using high-quality silica materials, chosen with great care to ensure exceptional purity and uniformity. The production process involves precise blending, shaping, and high-temperature firing, resulting in bricks that are both durable and reliable. With cutting-edge manufacturing facilities, we assure consistent quality and meet the rigorous requirements of diverse industries.

Production Process of Lightweight Silica Insulation Bricks
Put raw materials and water into a kneading equipment according to a certain proportion and then kneaded into mud. Shape the mud into bricks through molding by machine or manpower. Then dry the bricks till the residual water content is lower than 0.5%, which prevent the volume expansion from the crystal transformation of SiO2. At the end, fire the shaped bricks in the high temperature, but pay attention that increase and decrease the temperature slowly when firing.
