Changes in copper sulfate crystal habit during cooling crystallization

Strategies To Control Product Characteristics in Simultaneous Crystallization of NaCl and KCl from Aqueous Solution: Seeding with KCl

“…Coalescence of fluid inclusions has also been observed for batch cooling crystallization of copper sulfate. 32 3.2. Mass Balances.…”

“…Simultaneous crystallization studies have been reported with the NaCl–KCl–H 2 O system. At temperatures below say 400 °C isomorphic substitution is small, and thus only pure compounds of respectively halite and sylvite structures are formed. − Some impurity may be incorporated in the single crystals of each compound by liquid inclusions if crystals develop under high supersaturation. , The spontaneous nucleation of KCl upon the surface of a dissolving NaCl crystal has been observed even in undersaturated solutions with respect to both salts . Takiyama et al have reported the existence of a continuous solid–solid interfacial region between a KCl deposit and its NaCl substrate, which displayed different physical properties and lower stability in comparison to the pure compounds.…”

Nucleation and growth of CuSO4·5H2O crystals on the liquid state stearic acid Langmuir–Blodgett film

“…CuSO 4 Á 5H 2 O is produced by crystallization for use in agriculture as a mineral additive to animal foods, and in electronics as an intermediate [24]. More than 100 peaks appear in the XRD pattern of CuSO 4 Á 5H 2 O over the 2y range from 101 to 451.…”

Confocal fluorescence spectrometry for observation of crystal dissolution kinetics

“…These differences are attributable to relative differences in the sizes of crystal faces. Differences in crystal habits depend on the physical and chemical condition of crystal growth and dissolution, such as temperature, pressure, chemical composition of solution and trace elements in solution [6][7][8]. In other words, the morphological features in crystal habits are induced by differences in the rates of crystal growth or dissolution as a result of changes in the conditions.…”
