Final observed, collected and difference powder diffraction patterns for the Rietveld refinement of selected synthesized precipitates: (a) pyromorphite Pb10(PO4)6Cl2, (b) solid solution Pb10(PO4)3(AsO4)3Cl2 and (c) mimetite Pb10(AsO4)6Cl2. (d) Mimetite Pb10(AsO4)6Cl2 close-up of the region of interest containing additional peaks previously undetected (red circles). |
