Abstract

High-performance liquid chromatography (HPLC) measurements on crystalline and glassy Na4NbP3Oz prove that the crystalline phase is a pyrophosphate and that the glassy material contains a distribution of phosphate anions with anions up to five PO4 tetrahedra in length. Powder X-ray diffraction data for a new trimetaphosphate crystalline phase with the composition Na3NbP3Ox are also reported.
