water of crystallization

n
(Chemistry) water present in the crystals of certain compounds. It is chemically combined in stoichiometric amounts, usually by coordinate or hydrogen bonds, but can often be easily expelled

This increase in ML is quite slow up to a temperature of 300oC which could be the result of the elimination of moisture and water of crystallization. From that point and up to a temperature of 500oC the decrease in ML has a more abrupt trend suggesting that decomposition of the mineral occurs mainly in this region.
Thus, in the process of removing moisture by air-drying of the synthesized vanadium-containing gel, transition linkages occur from water of crystallization to OH groups, thus forming the layered structure fibers of VO chains and water molecules.
