The difference between refractory brick and ordinary brick

2021-09-17 17:06:33

Refractory bricks are refractory ceramic blocks used to connect fireplaces, fire boxes and stoves. They are different from ordinary masonry bricks because they can withstand temperatures up to 1800 degrees Fahrenheit. The chemical composition of dense refractory bricks is different from ordinary bricks. Refractory bricks in color, shape and thermal conductivity

Silica bricks are used more in glass melting furnaces, and the main component is silica (SiO2). The silica brick used in the glass melting furnace requires a SiO2 content of 94% or more, a maximum use temperature of about 1600 to 1650 ° C, and a density of 1.8 to 1.95 g/cm 3 . The apparent porosity requirement is less than 22%, the larger the porosity, the worse the quality of the silica brick.
