However, the effects of mixing are different from the effects induced by US, with the crystals obtained under sonicated conditions being superior in terms of uniformity with respect to size and shape [14], [73], [85], as it is shown in Fig. 5. Crystals obtained with sonication are more regular, and no agglomeration has been detected.

During sonication, the solvent and decomposition products volatilized, thereby lowering the specific heat ratio and average temperature in the bubble. When the vapor pressure is extremely low, the solvent does not volatilize into the cavitation, so the obtained average temperature was assumed to be the cavity temperature without …
