Item type:Article, Access status: Open Access , Halogen substitution in synthetic lead apatite compounds Raman spectroscopy study(Wydawnictwa AGH, 2014) Witkowska, Małgorzata; Motyka, Joanna; Kwaśniak-Kominek, Monika; Manecki, MaciejMimetite $Pb_{10}(AsO_{4})_{6}Cl_{2}$, vanadinite $Pb_{10}(VO_{4})_{6}Cl_{2}$ and pyromorphite $Pb_{10}(PO_{4})_{6}Cl_{2}$ are minerals isostructural with apatite occurring in the oxidation zones of Pb deposits. They exhibit hexagonal structure and rod-shape morphology.Item type:Article, Access status: Open Access , Optimization of synthesis conditions of pyromorphite-vanadinite and mimetite-vanadinite solid solution series(Wydawnictwa AGH, 2014) Janicka, Urszula; Bajda, Tomasz; Topolska, Justyna; Manecki, MaciejMinerals: pyromorphite $Pb_{5}(PO_{4})_{3}Cl$, mimetite $Pb_{5}(AsO_{4})_{3}Cl$ and vanadinite $Pb_{5}(VO_{4})_{3}Cl$ belong to the apatite supergroup. Commonly they form in hypergenic conditions. They are best known from the oxidation zones of lead ore deposits.Item type:Article, Access status: Open Access , Structural and vibrational behaviour of pyromorphite-vanadinite solid solution series(Wydawnictwa AGH, 2015) Solecka, Urszula; Bajda, Tomasz; Topolska, Justyna; Manecki, MaciejPyromorphite $Pb_{5}(PO_{4})_{3}Cl$ and vanadinite $Pb_{5}(VO_{4})_{3}Cl$ belong to the apatite supergroup. They are secondary minerals formed in the oxidation zones of lead ore deposits.Item type:Article, Access status: Open Access , The Rietveld refinement studies of pyromorphite-vanadinite and mimetite-vanadinite solid solution series(Wydawnictwa AGH, 2016) Solecka, Urszula; Zelek-Pogudz, Sylwia; Bajda, TomaszMimetite $Pb_{5}(PO_{4})_{3}Cl$, vanadinite $Pb_{5}(VO_{4})_{3}Cl$ and pyromorphite $Pb_{5}(PO_{4})_{3}Cl$ belong to the apatite supergroup.
