Crystalline hydrate

WebCalcium silicate hydrate is produced by reaction of C3 S or C 2 S with water. It is frequently described as a gel rather than a crystalline material because no consistent structure is discernible using X-ray diffraction. Its composition is also variable but stoichiometrically it usually contains approximately twice as much CaO as SiO 2 plus a ... WebDec 1, 2024 · Several common deliquescent crystalline food ingredients (including glucose and citric acid) are capable of forming crystal hydrate structures. The propensity of such crystals to hydrate/dehydrate or deliquesce is dependent on the environmental temperature and relative humidity (RH).
