The siliceous firebrick is a siliceous refractory product with more than 90% SiO2 content and a volume density less than 1.2g/cm³. The mineral composition of silicon fire brick is: phosphorus quartz 78% ~ 86%, quartzite 13% ~ 15%, quartz 4% ~ 7%. Siliceous heat insulation firebrick generally adopts crystalline quartzite or silica sand as raw material, and flammable substances are added to the ingredients, such as coke, anthracite, sawdust, carbonized rice husk or porous structure is formed by gas foaming method. The refractoriness and softening temperature under load are not much different from those of ordinary light silicon bricks with the same composition. But because there are many pores, so the compressive strength, slag resistance, corrosion resistance is not as good as the ordinary light silicon brick, and the thermal shock resistance has been improved.
