    Silica Lightweight Refractories Material​ is also known as silica insulation brick. Lightweight refractories with silica above 91% and bulk density below 1.2g/cm3. The refractoriness and load softening temperature are not much different from ordinary silicon bricks with the same composition.


    However, due to the large number of pores, the compressive strength, slag resistance, and corrosion resistance are not as good as others silicon bricks, but the thermal shock resistance has been improved.

    Using finely divided silica as raw material, the critical particle size is usually not more than 1mm, and the particles less than 0.5mm are not less than 90%. 


   Silica Lightweight Refractories Material​ is mainly used in various parts of the kiln that require heat insulation or reduce its own weight without direct contact with the melt, without the action of aggressive gases, or with sudden temperature changes. When used at high temperature, it must not be in contact with alkaline refractories. According to different materials, the maximum service temperature is 1200~1550℃.






    (1)  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

    (2)  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.

    (3)  Small shrinkage value: The excellent material with a small shrinkage value ensures that your wall will not crack.

    (4)  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.

    (5)  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.


    (6)  Silica Lightweight Refractories Material​  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.




    Silica Lightweight Refractories Material​  are also used in the partition walls of the carbonization and combustion chambers of coke ovens, the regenerators and slag chambers of open hearth furnaces, soaking furnaces, glass melting furnaces, refractory materials and ceramic firing kilns. There are also vaults and other load-bearing parts for kilns. It is also used for the high-temperature load-bearing part of hot blast stove and the top of acidic open hearth furnace.
