At its base level, crystallization is the isolation of a solute from a solvent by causing it to form a solid. This is achieved by manipulating the solute’s solubility in the solvent. The most common way to achieve this is through the manipulation of temperature. This is referred to as a cooling crystallization and this is what is used to ...

Aug 01, 1982 Here, the rate of crystallization is about a factor of 10 greater than the deacti- vation rate in the fixed-bed reactor studies. Using the rate equation given in Part I (/), the deactivation rate with 2.8% HzO in air is 0.5 hr~1 while the crystallization rate ob- served under these conditions is 0.06 hr1.

Crystallization in a supercooled liquid or a glass occurs via a nucleation-growth mechanism which starts by the formation of small ordered germs. The germination can be enhanced by the presence of rough interfaces in the melt. Figure 4 gives an example of nucleation and growth curves for a glass. Figure 4.

Description of the crystallization setup The crystallization is conducted in a thermostated, 250 ml jacketed glass reactor (see gure 4(a)) equipped with a stirrer. A thermostat pumps a mixture of glycol and water through the jacket and uses a Pt100 thermocouple positioned in the reactor to control the reactor temperature.

For the crystallization studies we used a Slurry Flow Cell connected to a Malvern dispersion unit (Hydro 2000SM). The dispersion unit was set to 1500 – 2000 rpm to pump the slurry through the measurement flow cell. The cell was integrated on a PANalytical Theta-Theta diffractometer system, positioned in a transmission geometry mode. The ...
