    Light Weight Silica Fire Brick​  refer to heat-insulating refractory products made of silica as the main raw material and with an SiO2 content of not less than 91%. In addition to the thermal insulation properties of Insulating silica bricks, it maintains the characteristics of silicon bricks to a large extent. The starting temperature of load softening is high, and the volume expands slightly during the heating process, which enhances the integrity of the kiln. The manufacture of siliceous Insulating silica bricks uses finely pulverized silica as the raw material, adding part of the waste silica bricks or waste siliceous Insulating silica bricks powder, mineralizers and burnout additives. Add water to the mixer according to a certain proportion to mix into a mud, which is formed by mechanical or manual molding. After the brick is dried, the residual moisture is less than 0.5% before it can be loaded into the kiln. In order to prevent the violent volume expansion due to the polycrystalline transformation of SiO2, causing cracks in the product, a slower temperature rise and fall speed are required during firing.℃.
    (1)  Light weight: using this product in construction can reduce the weight of the building and greatly reduce the comprehensive cost of the building.
    (2) Insulation and heat insulation: During the manufacturing process of aerated concrete, tiny pores are formed inside, and these pores form an air layer in the material, which greatly improves the effect of thermal insulation
    (3) Sound absorption and sound insulation: good sound absorption and sound insulation performance can create high airtight indoor space for you. Provide you with a quiet and comfortable environment.
    (4) Small shrinkage value: The excellent material with a small shrinkage value ensures that your wall will not crack.
    (5) Impermeability: The pore structure of this product makes the capillary action poor, and the water absorption and moisture conduction are slow. The time required for the same volume of water absorption to saturation is 5 times that of clay bricks.
    (6) Environmental protection: no pollution during manufacturing, transportation and use, protect cultivated land, save energy and reduce consumption, and belong to green environmental protection building materials.
    (7) Light Weight Silica Fire Brick​ ​​ is also a light-weight heat-insulating brick. It has a higher heat resistance temperature than light-weight clay bricks. It can be used in heat-insulating parts to reduce heat loss and increase the efficiency of the melting process.
    Light Weight Silica Fire Brick​ ​​ are widely used for hot blast furnace, coke oven, and glass furnace. The products can be made according to customers' requirement.
