Silica gel and what reacts to produce silica?
Silica gel is the main component of silica, chemical stability, not burning.Silica gel alias: silicic acid gel, is a highly active adsorption material, chemical formula is mSiO2 nH2O; in addition to strong alkali and hydrofluoric acid, not with any substance reaction, insoluble in water and any solvent, non-toxic, tasteless.Therefore, silica gel does not react with other substances to form silica.
No reactants are needed, plus strong heat.Silica gel (Silica gel; Silica) alias: silica gel is a kind of high active adsorption material, belonging to the amorphous material, its molecular formula is mSiO2 nH2O; in addition to alkali, hydrofluoric acid does not react with any material, insoluble in water and any solvent, non-toxic, chemically stable.
As can be seen from the molecular formula, the silica gel is actually hydrated silica. Under intense heat, the reaction has a decomposition reaction to produce water and silica. This reaction equation
