Liquid-liquid interfacial crystallization was proposed as a novel method for controlling the crystal shape and size. The crystallization was performed at interfaces forming two separate phases of aqueous solution and organic solvent in the present study, and progressed with increases of supersaturation caused by the slightly mutual diffusion in the liquid-liquid system. This crystallization process can precipitate particles at room and constant temperature without cooling or heating sources. The liquid-liquid interfacial crystallization method was able to change the shape of the interface.A spherical shape was formed in droplets made by 3-way nozzle in the present liquid atomization process. The droplets of the solution sprayed into the organic phase. The collision between the solutions from the nozzle in compressed air produced the micro-size droplets of the solution. In the 1-butanol liquid, NaCl and glycine crystallized at their liquid-liquid interface and the spherical aggregated particles were obtained. The aggregated NaCl particles had a hollow structure and the glycine particles were porous.
