    Silica Insulating Fireproof Bricks​​ are made with raw material high grade bauxite and SiC and special sintering process. Silica-mullite bricks are characterized by high density, good performance of abrasion resistance and thermal shock resistance. It can constantly form protective layer for reducing accrection formation, long application cycle,etc.


   Silica Insulating Fireproof Bricks​​​ 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)  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) Silica Insulating Fireproof Bricks​​ 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.




1). Gas cooker,Water heater,Gas oven, Gas boiler,Air-conditioning and so on.

2). As ceramic parts of flexible pad and channel heaters at operations of pre and postweld heat treatment; Welding process, stress-relieving, pre-heating & post heating, other resistance-heating environment
3). halogen lamps, high and low pressure uv lamps, mercury lamps, uv lamp holders and heating tubes.

4). high-power electrical applicance and all kinds of insulation device.
