X-ray diffraction characterization of the untreated calcium phosphate from two Moroccan mining zones

Abstract

X-ray diffraction (XRD) analyses were performed on untreated calcium phosphate samples of the two mining zones of Morocco: Benguerir and Khouribga. XRD was investigated for the determination of the structure. However, a comparative study was carried out between the two types of phosphate to implement the observed differences. Results showed that the comparison between the two samples reveals significant differences at the level of the refinement parameters, crystallite size and microstrain but no changes in the crystal system.
