Web30 jul. 2024 · Hydrated amorphous phases were built introducing a number of water molecules between 4 and 8 with a total number of urea + H 2 O molecules of ten in all calculations. When water molecules closely interact with urea through hydrogen bonds, several configurations have been investigated (see also ESI † ). WebThe structure of the hydrated phosphates is proposed to consist of both short phosphate chains and isolated phosphate groups linked together by hydrogen bonds. Containing up to 40 mol% of water, most of the physicochemical properties remain unchanged, except for the characteristic glass temperatures.
