中文摘要：

新 niobale 混合物第一次被综合 inNa_2O-BaO-Li_2O ) 由稳固的陈旧反应的 -ZnO-Nb_2O)_5 系统。新混合物被 X-raydiffraction，电子探查， X 光检查微量分析，化学分析和 SEM 学习。X-raypowder 衍射的结果证明 NaBa_2 Li_(0.6 )Nb_(4.8 )Zn_(0.2 )O_(15 ) 属于 orlhorhombictungsten 铜结构，与空间群 Pba2 (32 ) 和点阵参数 =12。6115 (2 ) 一， b =12.4981 (2 ) A， 6 号元素碳的化学符号 = 3.9479 (3 ) 一。混合物的 X 光检查粉末衍射线很好被索引。

英文摘要：

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 acw 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 compoutid were well indexed.
