摘要：
Studying the textures (the preferred orientation of the nanometer building blocks) in the structures of neodymium tungstates shows that infinite dimeric bands {[LnO(n)]-[LnO(n)]}-{[LnO(n)]-[LnO(n)]} in a fluorite-like 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 Ln(2)O(3) (a fluorite-type structure) and the acid oxide WO3 (a ReO3-type structure).
