Description
Summary:TB3; A new niobate compound was synthesized for the first time in Na2 O-BaO-Li2 O-ZnO-Nb2 O5 system by solid state reaction.The new compound was studied by X- ray diffraction, electron probe, X- ray microanalysis, chemical analysis and SEM.The result of X-ray powder diffraction shows that NaBa2 Li0.6 Nb4.8 Zn0.2 O15 belongs to orthorhombic tungsten bronze structure, with .space group Pba2 ( 32 ) and lattice parameters a =12.6115(2)(A), b = 12.4981 (2)(A), C = 3.9479(3)(A).The X-ray powder diffraction lines of the compound were well indexed.
