Rietveld refinement of the models of the SRD data collected from the synthesized HAp–5%C mixed sample for a selected 2θ range. The observed plot is the crosses, the calculated plot is the continuous line through the observed data, the upper set of vertical lines underneath the plot represent the peak position markers for a hexagonal hydroxyapatite phase [Ca10(PO4)6(OH)2], the lower set of vertical lines are for the rhombohedral β-calcium phosphate phase [β-Ca3(PO4)2], and the difference plot is below the peak markers. |
