The formation of liquid inclusions is frequently observed to be disrupting in crystallization processes. But such crystals containing liquid inclusions might offer the possibility to be used as container systems by encapsulating other substances inside the inclusions. Experimental parameters to generate such microcontainer systems, i.e., crystals including liquid inclusions, of salicylic acid by means of antisolvent crystallization were investigated. It was shown that concentration, addition rate of the antisolvent, and gas content of the liquids related to the temperature have a distinct influence on the size of the formed inclusions.
