The calcium to phosphate atomic ratio (Ca/P) in calcium phosphates powders was characterized by using X-ray diffraction analysis (XRD). The calcium phosphate powders with various stoichiometric Ca/P molar ratio were synthesized with co-precipitation process and calcination. Compositions of the powders with Ca/P molar ratio (0.5, 1.0, 1.33, 1.5, 1.67, 2.0) were subjected to starting Ca/P molar ratio, pH 11, and thermal treatment up to 1000℃. The structural and morphological characterizations for calcium phosphate powders with stoichiometric Ca/P molar ratio were carried out with scanning electron microscope (SEM) and a phase quantification was investigated by XRD. |
