|Title:||Formation Of Oxysulfide Lno 2s 2 And Oxysulfate Lno 2so 4 Phases In The Thermal Decomposition Process Of Lanthanide Sulfonates (ln = La, Sm)|
De Azeredo M.T.D.

|Abstract:||This study investigates two lanthanide compounds (La 3+ and Sm 3+) obtained in water/ethyl alcohol solutions employing the anionic surfactant diphenyl-4-amine sulfonate (DAS) as ligand. Both sulfonates were characterized through IR, TG/DTG (O 2 and N 2). The thermal treatment of both compounds at 1273 K under air leaves residues containing variable percentages of lanthanide oxysulfide/oxysulfate phases shown by synchrotron high-resolution XRD pattern including the Rietveld analysis. The phase distributions found in the residues evidence the differences in the relative stability of the precursors. © 2011 Akadémiai Kiadó, Budapest, Hungary.|
