| Summary: | The study utilized marine mollusks, Conasprella bermudensis, and Oliva sayana, to manufacture nano dicalcium phosphate dihydrate (DCPD), a bio-ceramic material having an increased Ca/P ratio, which was characterized using X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). The produced DCPD nanoparticles exhibited a well-defined crystalline structure within the permissible nanometer range (1–150 nm), with crystallite sizes varying across different models. The estimated microstrain ranged from −6 × 10−4 to 3 × 10−4, while the calculated stress values varied between −1 × 107 and 6 × 106 Nm−2, and the energy density values were between 9.50 × 102 and 3.53 × 103 Jm−3. The (020) and (021) planes for both synthesized DCPD exhibited significant intensity, indicating that synthesis media influenced the crystallographic planes. FTIR spectra confirmed the presence of key functional groups, including P–O, CO32−, OH−, and H2O. These findings provide valuable insights into the structural and mechanical characteristics of nano-DCPD sourced from marine mollusks. |
