Silica insulating refractory brick refers to an insulating refractory product made of silica as the main raw material and having a SiO2 content of not less than 91%.
In addition to its thermal insulation properties, silica insulating refractory bricks maintain the characteristics of silica bricks to a large extent. The load softening starts at a high temperature. During the heating process, the volume expands slightly, which enhances the integrity of the furnace.
