Crystal growth of clathrate hydrate formed with H2 - Nature

WebHowever, for ethanol hydrate and some of the amine hydrates, which melt incongruently, there are very narrow concentration ranges in which a pure crystalline hydrate can be obtained. Like the hydrophobic guest components, these soluble liquids also form double hydrates with a third molecular species, such as H2S, which then functions as a help gas. WebCalcium silicate hydrate (also shown as C-S-H) is a result of the reaction between the silicate phases of Portland cement and water. This reaction typically is expressed as: 2 Ca 3 SiO 5 + 7 H2O → 3 CaO · 2 SiO 2 · 4 H2O + 3 Ca (OH)2 + 173.6 kJ. also written in cement chemist notation, (CCN) as:
