WebSingle-crystal hydroxyapatite (HAp) nanorods and nanogranules have been synthesized successfully by a mechanochemical process using two distinct experimental procedures. The experimental outcomes are characterized by transmission electron microscopy (TEM), and powder X-ray diffraction (XRD) techniques. In this work, the feasibility of using … WebFigure 3 XRD pattern of the synthesized HA. Abbreviations: XRD, X-ray diffraction; HA, hydroxyapatite. Figure 3 shows that all the peaks from the sample pattern match with those of the 09-0432 JCPDS diffraction card provided …
