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.
