【摘要】 以SrNb₂O₆-BaNb₂O₆的赝二元体系相图为基础来合成这个体系中的3种物质,根据X射线粉晶衍射图谱中显示数据的分析,发现了相图中的端元相SrNb₂O₆、BaNb₂O₆和中间相Sr_0.5Ba_0.5Nb₂O₆在结构上的不连续性。计算了3种合成晶体的晶胞参数和化学分子式。更多还原

【Abstract】 Three kinds of crystals were prepared on the basis of the binary phase diagram of the Barium Niobium Oxide-Strontium Niobium Oxide system. Using X-ray diffraction and electronic probe microscopic analysis. the crystal structure of the crystal was examined, and it was found that their crystal structures changed djscontinu-ously. Cell parameters and chemical formula of these crystals were also determined.更多还原
