Modification of the crystallographic parameters in a biomaterial employing a series of gamma radiation doses
A well-known biomaterial, hydroxyapatite (HAp), was synthesized by employing a wet chemical precipitation method utilizing orthophosphoric acid and calcium hydroxide. Different doses of gamma radiation such as 20, 30, 60, and 80 kGy were applied through HAp. These gamma irradiated HAp samples were c...

Summary: | A well-known biomaterial, hydroxyapatite (HAp), was synthesized by employing a wet chemical precipitation method utilizing orthophosphoric acid and calcium hydroxide. Different doses of gamma radiation such as 20, 30, 60, and 80 kGy were applied through HAp. These gamma irradiated HAp samples were characterized by utilizing X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and UV-vis spectrophotometry. A number of crystallographic parameters such as lattice parameters, dislocation density, microstrain, the degree of crystallinity, crystallinity index, HAp percentage, β-tricalcium phosphate (β-TCP) percentage, volume fraction of β-TCP, and specific surface area were calculated from the XRD data along with the crystallinity index (measuring height, area, and FWHM) from FTIR. All the mentioned crystallographic parameters presented a gradual change when gamma radiation doses were intensified.
