Silicone Heat insulating Refractory Fire Brick generally use crystalline quartzite or silica sand as raw materials, and the mineral composition is: phosphorite 78% to 86%, cristobalite 13% to 15%, and quartz 4% to 7%. Add combustible materials to the ingredients, such as coke, sawdust, anthracite, carbonized rice husk, or use gas foaming to form a porous structure. Insulating silica brick Price are heat-insulating silicon refractory products with a SiO2 content of more than 90% and a bulk density of less than 1.2. The refractoriness and softening temperature under load are not much different from ordinary silica bricks with the same composition. However, due to the many pores, the compressive strength, slag resistance, and corrosion resistance are not as good as ordinary silica bricks, but the thermal shock resistance has been improved. It is similar to the production process of ordinary silica bricks. Some mineralizers (CaO, Fe2O3) are added to the ingredients to promote the conversion of quartz, and pulp waste liquid is used as a binder to make the bricks have a certain strength. When using coke or anthracite as combustible additives, because the ash will be brought into Fe2O3 and Al2O3, there is no need to add iron scales in the ingredients. When the siliceous Insulating silica bricks are fired, a strong oxidizing flame should be maintained before 1200°C to make the additions burn out completely.


    Silica Insulating brick 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℃.



The silica brick for coke oven has low alkali and low content of residual quartz.

The silica brick has high strength and refractoriness under load.

The silica brick also has strong ability in acid slag resistance.

This silica brick is used to the walls, hearth or other parts of the combustion chamber, and carbonization chamber




  1.  in the blast furnace blast area and communicate with the blast furnace exhaust.

  2. hot blast stove

  3.  in the partition walls of the carbonization and combustion chambers of coke ovens,

  4. the regenerators and slag chambers of open hearth furnaces, soaking furnaces, glass melting furnaces, refractory materials and ceramic firing kilns.

  5.  other load-bearing parts for kilns.

  6. high-temperature load-bearing part of hot blast stove and the top of acidic open hearth furnace.
