How to improve the crystal purity of crystallizer
During the operation, the supersaturation of the control mold is located in the stable zone. Mixing plays an important role in supersaturation and nucleation formation, which is the basis of crystal design.
Optimize the input of stirring energy for crystallizer. The supersaturation generated by this process is consumed by the growth of the crystal to its state, thus completing the cycle. If supersaturation is not completely consumed in one cycle, it will be further saturated in the next. After some time, the whole cycle will be far away from or even above the stable zone, which will adversely affect the growth and core of the crystal. Therefore, it is important to provide adequate crystal surfaces for supersaturated liquids. Otherwise, the grain shape will be destroyed。
Selecting proper supersaturation can make the growth rate of crystal nucleus larger.
