Abstract
Cerium(III) carbonate is a precursor material for the synthesis of various Ce-containing compounds. In this work, a synchrotron powder X-ray diffraction study of commercially obtained 'cerium(III) carbonate hydrate' indicates that multiple Ce-containing phases are present. The majority phase CeCO3OH (52.49%wt) was refined using an orthorhombic Pmcn structure model with a = 5.01019 (2) A, b = 8.55011 (4) A and c = 7.31940 (4) A, which is based on a reported structure for the lanthanoid carbonate mineral ancylite. Additionally, a substantial portion of the precursor material is cubic cerium(IV) oxide (47.12%wt).
