Silica Checker Brick
Silica refractory materials are acidic refractory materials that have good resistance to oxides such as CaO, FeO, Fe2O3, etc., and have the advantages of high softening temperature under load, stable volume at high temperatures, and high thermal conductivity. However, the thermal stability at low temperatures (below 800C) is poor. The specific manifestations are as follows: the load softening temperature can be as high as (1640-1680C), which is close to the melting point of tridymite (1670C), and the thermal stability above 800C is very good, which can Adapt to large changes in temperature.

The specific manifestations are as follows: the load softening temperature can be as high as (1640-1680°C), which is close to the melting point of tridymite (1670°C), and the thermal stability above 800°C is very good, which can Adapt to large changes in temperature.
Features
1.High Thermal Stability: These bricks exhibit excellent thermal stability and can withstand high temperatures without significant deformation or structural damage.
2.Low Thermal Conductivity: They have relatively low thermal conductivity, which helps in maintaining insulation and preventing heat loss in the furnaces or kilns where they are used.
3.Checker Design:This design is used to create a checkerwork pattern in furnaces or kilns, allowing for efficient heat transfer and better airflow.
Application
Silica checker bricks are mainly used in blast furnace hot blast furnaces and flame furnaces.
The silica bricks used in hot blast stoves have tridymite as the main crystal phase. They have stable volume and low creep rate under high temperature loads. Their anti-adhesion properties are also better than other refractory materials. Proper use can make the structure of hot blast stoves more stable.
