| Abstract: | Studying the textures (the preferred orientation of the nanometer building blocks) in the structures of neodymium tungstates shows that infinite dimeric bands {LnOn]-LnOn]}-{LnOn]-LnOn]} in a fluoritelike structure field of the Nd2O3-WO3 binary system undergo fragmentation and modification. The structural background (staggered arrangement of polyhedra) is determined by the like effects of both the basic oxide Ln2O3 (a fluorite-type structure) and the acid oxide WO3 (a ReO3-type structure). |
