Dear Mikko, In view of Leonid's space group it could be a alpha-PbO2 type *di*oxide polymorph. Best regards Andreas On 25.10.2013 10:53, Leonid Solovyov wrote: Dear Mikko, Your XRD pattern is well approximated by an orthorhombic Pbcn structure with lattice parameters a=5.187, b=5.607, c

Dear Mikko, Your XRD pattern is well approximated by an orthorhombic Pbcn structure with lattice parameters a=5.187,   b=5.607,   c=5.311, which may present a new anisotropically disported polymorph of cubic (Ce?,Sn?)O4. Best regards, Leonid   **

Dear Rietvelders, I decided to completely embarrass myself and ask you a simple phase identification question. I’ve had some trouble in trying to figure out what’s going on with one measurement done in our lab. The sample is a ~30nm film heat treated in air at 500C, composition is Ce:Sn in clos
