The influence of ultrasound amplitude on nucleation kinetics and properties of the final product of borax decahydrate was investigated. Mechanical mixing in a stirred-batch crystallizer was performed by a straight-blade turbine (SBT) to ensure a complete suspension of crystals. The obtained results indicated that continuous sonication affects nucleation kinetics, but also the properties of the final product. An increase of the ultrasound amplitude decreases the metastable zone width which ultimately reflects on the final crystal size. Even though the mean crystal size was larger in the non-sonicated system, it seems that the application of ultrasound shifts the crystal size distribution from bimodal to monomodal. But the shift comes at the cost of a substantial increase in power consumption.

超声振幅对搅拌分批结晶器中十水硼砂结晶的影响

研究了超声振幅对十水硼砂最终产物成核动力学和性质的影响。通过直叶涡轮机 (SBT) 在搅拌间歇结晶器中进行机械混合，以确保晶体完全悬浮。获得的结果表明连续超声处理会影响成核动力学，但也会影响最终产品的性质。超声振幅的增加会降低亚稳态区域的宽度，这最终会反映在最终的晶体尺寸上。尽管在非超声系统中平均晶体尺寸更大，但超声的应用似乎将晶体尺寸分布从双峰转变为单峰。但这种转变是以功耗大幅增加为代价的。
