Clay bricks for glass kiln

The main components of clay bricks are Al2O3 and SiO2, Al2O3 content is 30%-45%, SiO2 is 51%-66%, density is 1.7-2.4g/cm3, apparent porosity is 12%-21%, and the highest operating temperature It is 1350～1500℃. In the glass industry, the bottom of the kiln is built with clay bricks. Working pool walls and passages, regenerator walls and arches, lower checker bricks and flue. As the temperature increases, the volume of clay bricks will increase. When the temperature exceeds 1450°C, the volume will shrink again.
