The Effects of Silica and A Nature Polymer on the Size and Properties of Nano-Hydroxyapatite

In this study, we compared the effects of silica and gelatin in nano hydroxyapatite nHA composite with pure hydroxyapatite. We have synthesized hydrothermal nHA gelatin template and silica. They the obtained samples were investigated by x-ray diffraction XRD and Fourier transform infrared spectroscopy FT-IR . Scanning and transmission electron microscopy SEM was used for characterization of particle size and morp- hology of the samples. The percentage of elements in the prepared composite was determined using energy- dispersive x-ray spectroscopy EDS . We have identified that the use of gelatin and silica as a coating agent for nHA contributes to the increase in the size of the particles.
