ABSTRACT:
Beta tricalcium phosphate (?-TCP) is a bioceramic widely studied for its excellent biocompatibility, osteoconductivity, and potential in bone regeneration. This study aimed to synthesize nanometric ?-TCP via a green route using Aloe vera extract and a conventional chemical route (Pechini method), followed by a comparative analysis of their structural and morphological characteristics. The samples were calcined at 800 °C for 1 hour and characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). XRD results confirmed the formation of ?-TCP in both methods, although the green route also produced calcium pyrophosphate. FTIR spectra showed characteristic phosphate group (PO?³?) bands in all samples. SEM analysis revealed distinct morphologies depending on the synthesis route. Both methods were effective for ?-TCP synthesis, but differences in structural and morphological properties were observed.
