A new niobate compound was synthesized for the first time in Na_2O-BaO- Li_2O-ZnO- Nb_2O_5 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 NaBa_2Li_ 0.6 Nb_ 4.8 Zn_ 0.2 O_ 15 belongs to orthorhombic tungsten bronze structure, with space group Pba2(32) and lattice parameters a=12.6115(2), b=12.4981(2), C=3.9479(3). The X-ray powder diffraction lines of the compound were well indexed.
