چکیده مقاله:
The aim of the present study was to prepare nano-sized calcium fluoride (CaF۲). Calcium fluoride nanoparticles were synthesized by CaCl۲.۶H۲O and ammonium fluoride. Nanoparticles were synthesized by co-precipitation method. The synthesized nanocrystals were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM). The crystallite size estimated using Scherer’s formula was found to be in the range of ۲۰–۳۰nm for nanocrystals synthesized by this method. The morphological features as studied using SEM revealed that the nanoparticles were agglomerated, crispy with porous.
