用衍射仪和Guinier聚焦照相机收集了铌酸锶钡钠系统一系列化合物的X射线粉末衍射图谱(CuKα辐射)。给出了Ba2NaNb5O15,SrBaNaNb5O15和Sr2.05Na0.90Nb5O15详细指标化了的粉末衍射数据,可代替原有的JCPDSX射线粉末衍射标准数据卡(卡片号为23-654,27-1408,27-1409和27-787)的数据。The X-ray powder diffraction patterns of various compounds of sodium strontium barium niobate system were obtained with a counter diffractometer and a Guinier focusing camera using CuKα radiation. The detail indexed powder diffraction data for Ba2NaNb5O15, SrBaNaNb5O15 and Sr2.05Na0.90Nb5O15 were given. These data may replace those presented in the JCPDS X-Ray Powder Diffraction Standards Data Pile (Cards No. 23-654, 27-1408, 27-1409, 27-787).
