Abstract: The effect of sodium fluoride addition on the crystallization of cholesterol has been studied. It has an inhibitory effect, which not only reduce the growth rate and number of crystals but also change the morphology of the cholesterol crystals. The crystal structure, morphology and thermal properties have been analyzed using powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and TG-DSC studies. Functional groups and fluoride doping in the grown cholesterol crystals have been confirmed from the vibrational frequencies of the recorded FTIR spectrum. Results of this study shows that the increase of fluoride content in the growth environment suppresses the formation of cholesterol.
