Effect of ultrasonic-induced selenium crystallization behavior during selenium reduction

Evaporating crystallization effect of ammonium sulfate at atmospheric pressure under the action of ultrasound

“…Therefore, the optimal experimental conditions for subsequent experiments are determined to be 360 W. The regulatory effect of ultrasound power on particle morphology has also been reported in other studies. Yang et al [26] studied the effect of ultrasound on the crystallization of selenium and reported that as the ultrasound power increased, the selenium crystals split from large particles into more small selenium particles with a columnar structure and gradually grew into selenium nanorods. Lucija Majal et al [27] also found that an increase in ultrasound power caused the transformation of the ticagrelor crystals from agglomerated cubes to agglomerated rods, and finally to agglomerated needles, indicating that an increase in ultrasound power could transform large particles into smaller particles with more uniform particle sizes.…”
