Figure 1
The crystal structure and the powder XRD data of Pb5(PO4)3OHδ. (a) shows the crystal structure of Pb5(PO4)3(OH) from single-crystal XRD and a comparison of Pb atom distribution between the orthorhombic and hexagonal structures. (b) Powder XRD data of Pb5(PO4)3OHδ from in-laboratory diffraction measurements. The experimental data are plotted as red dots. The black line gives the Rietveld refinement. The blue line indicates the corresponding residual pattern (difference between observed and calculated patterns). Bars give Pb5(PO4)3OHδ peak positions from single-crystal XRD measurement. The green arrow indicates the peak from an impurity. On the upper right of the figure, a picture of the crystals is shown; the size of the chunk is about 5 mm. |
