Modern ultrasound induction is very much useful in crystallization process. It uses piezoelectric transducers or quartz crystals to convert mechanical waves to electrical signals and vice versa. Growth of a crystal is environment dependent. The characteristics of grown crystals depend on impurities, temperature, preparation of the solution and mechanical agitation. The properties and size of a crystal can be tailored by controlling any one or all the above factors. The most interesting fact is that the ultrasound influences the properties and size of a crystal. It is found that the characteristics are improved and tailored for a specific need of the industry when a crystal is grown by radiating ultrasonic wave. In some cases, it produces nanocrystals. We used a device which generates the Ultrasonic wave of 15 MHz, which is applied to the crystal right from the time before nucleation till the crystal formation. The Dextrose monohydrate crystals are grown by conventional slow cool batch method. In the same slow cool batch method, Ultrasonic waves of 15 MHz are allowed to pass, influence the nucleation, crystal formation and growing process. The crystal formation process under the exposure of Ultrasound is allowed to continue for a sufficiently long time to yield the desired nanocrystals. The FTIR, UV, microhardness and SEM analysis are taken for the crystals with and without ultrasound.
