Enhancing Crystal Quality with High Shear Stress in Continuous Flow<\/h3>\n\n\n\n

Takiyama Research Group has developed a new method to improve the quality of crystalline particles during reactive crystallization. By using a continuous flow with high shear stress, known as Taylor vortex flow, they were able to study how different operation points on the phase diagram affect crystal quality. This method helps to maintain consistent conditions and prevent particle agglomeration.<\/p>\n\n\n\n

The study found that factors like solution pH and supersaturation significantly impact the aspect ratio and size distribution of the crystals. By carefully designing an operation strategy that considers these factors, the researchers were able to produce higher quality crystalline particles. This approach clarifies the relationship between operation points and crystal quality, offering a promising strategy for improving crystallization processes.<\/p>\n\n\n
