Abstract

The seeded sonocrystallization of calcite was investigated by measuring the volumetric crystallization rate at constant composition conditions. The crystallization rate of calcite was enhanced by 46% through ultrasonic irradiation (42,150 Hz, 17 W dm-3) of a supersaturated crystal suspension. It was shown that this effect was related to the alteration of the seed crystals' habit and size. During ultrasonic irradiation disruption of conglomerates and erosion of single crystals occurred, accompanied by the production of many fines. The increased surface area available for crystal growth resulted in the observed crystallization rate enhancement.
