Cooling crystallization
Thread Content
Seniors! I work with crystallization; I use cooling to induce crystallization. How can I make the crystal particles uniform?
Adding stirring can help to refine the crystals evenly
Even with stirring, it’s still not uniform. Could there be a problem with the cooling process?
The nucleation rate and growth rate should be controlled, that is, the degree of supersaturation should be controlled. It is determined based on the specific process; first, the number of nuclei is controlled
What is the general range for saturation? How to control it?
I’m not sure what substance it is. To achieve uniform crystallization, it’s necessary to control the formation of crystal nuclei as well as their growth rate; the key factors are saturation level, temperature, and time. It’s recommended to conduct experiments or look up some relevant information
It is necessary to control the speed of stirring, as well as the speed of cooling. There should also be an appropriate saturation level
