The *.jpeg file provides a visual comparison overlaying the X-ray diffraction (XRD) patterns of all 8 investigated hydroxyapatite samples against a standard reference pattern (from the COD / ICDD database). This comparison clearly illustrates the phase purity, the presence or absence of secondary impurity phases, and variations in the crystallinity degree (indicated by peak intensity and broadening) relative to the ideal stoichiometric hydroxyapatite standard.928839289892902928789284992882929099288023856175273application/octet-streamapplication/octet-streamapplication/octet-streamapplication/octet-streamapplication/octet-streamapplication/octet-streamapplication/octet-streamapplication/octet-streamimage/jpegtext/plain1.0CC0 1.0This dataset comprises X-ray diffraction (XRD) patterns for 8 distinct hydroxyapatite samples. The data was collected using an AXRD Benchtop diffractometer to determine phase purity, identify crystalline phases, and calculate lattice parameters for each sample.During data processing using the PDPAnalysis software, the following procedures were carried out: - Background fitting and subtraction. -Diffraction peak searching, including the determination of their exact positions and profiles. -Phase identification by matching the experimental data with the international Crystallography Open Database (COD).Ministry of Education and Science of Ukraine0126U001407
