The most valuable property of silica bricks is a very high RUL which is because of this tridymite bond Silica brick with an apparent density of about 1800 kg/m 3 is a fairly light brick—an advantage in some of its appliions over alternatives An important appliion of silica bricks is in the domes and upper checkerwork of cowper stoves
2009316 In addition since the fine particles in the firing process are easy to be transformed into tridymite the fine particles are mostly added The generally used mineralizing agents include FeO CaO and MnO For coke oven silica brick 2 CaO and 2 MnO are added For highdensity highSiO2 silica bricks 08 FeO and 02 CaO are added
Silica Brick Description SiO2 and CaO can form CaOSiO2 it is easily attacked by alkaline substances such as NaOH It has been found that the CaOSiO2 phase is the main cause of corrosion of silica bricks in glass kiln The reaction of the CaOSiO2 phase with NaOH forms a glass phase in the silica brick and gradually dissolves the SiO2
