Name and formula Reference code: 00-043-1002 Mineral name: Cerianite-(Ce), syn PDF index name: Cerium Oxide Empirical formula: CeO2 Chemical formula: CeO2 Crystallographic parameters Crystal system: Cubic Space group: Fm-3m Space group number: 225 a (?): 5.4113 b (?): 5.4113 c (?): 5.4113 Alpha (°): 90.0000 Beta (°): 90.0000 Gamma (°): 90.0000 Calculated density (g/cm^3): 7.21 Volume of cell (10^6 pm^3): 158.46 Z: 4.00 RIR: 13.20 Subfiles and Quality Subfiles: Inorganic Mineral Alloy, metal or intermetalic Quality: Calculated (C) Comments General comments: Calculation of diffractometer peak intensities done with MICRO-POWD v. 2.2 (D. Smith and K. Smith) using default instrument broadening function (NBS Table), diffracted beam monochromator polarization correction, and atomic scattering factors corrected for anomalous dispersion. Cell parameters from 34-394. Atomic positions from Wyckoff for fluorite structure with Ce in 4a and O in 8c. Isotropic thermal parameters estimated as 1.0 for each atom. Additional pattern: See ICSD 61595 (PDF 01-078-0694); ICSD 72155 (PDF 01-081-0792).
