Role of buoyancy driven convection in aqueous solution growth; A case study of Ba(NO3)2 crystal

Using Schlieren technique and Mach-Zehnder interferometry, the diffusion boundary layer and buoyancy driven convection around a growing barium nitrate crystal from the aqueous solution were visualized and their effect upon the growth kinetics of crystals was investigated in relation to the bulk supersaturation. It was demonstrated that buoyancy driven convection plumes behaved differently depending on the bulk supersaturation, and that their...
