Abstract

In this article, the study of the influence of the calcination temperature on the crystallographic, compositional, and morphological properties of the natural hydroxyapatite taken from sheep bones was carried out. The obtained samples were characterized by thermogravimetric analysis (TGA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy, with elemental analysis (SEM-EDS) in order to obtain structural information, compositional and morphological properties. In the thermogravimetric curves, the decomposition temperatures of the organic phases present in the sheep bones powder were identified. In the X-ray diffraction analyzes, it was found that the diffraction patterns presented characteristic peaks of hydroxyapatite and, it was observed that the increase in temperature favors the growth crystallite size. Likewise, in the morphological analysis, changes in the samples were verified, finding greater agglomeration of the particles, while the EDS analyzes revealed the different Ca/P relationships for the calcination temperatures used. In the FTIR spectra, the characteristic vibrational bands of the phosphate and hydroxyl functional groups present in the samples were observed. Moreover, due to the temperature changes, the vibrational bands corresponding to water and proteins disappeared, and a decrease in the carbonate bands was also identified.
