  Phase equilibria in the system CePO4 - NaPO3

  摘要：

  The system CePO4-NaPO3 was investigated by differential thermal and X-ray analyses and infrared spectroscopy and its phase diagram was established. The system contains only one intermediate compound, NaCeP2O7, which melts incongruently at 800-degrees. It exhibits a polymorphic transition at 595-degrees. The low-temperature modification has an orthorhombic unit cell with the parameters.a = 5.28, b = 12.65, c = 4.31 angstrom, alpha = beta = gamma = 90-degrees and V = 288.1 angstrom 3.

  Abstract Sodium rare earth diphosphates NaLnP2O7 (Ln = Ce (1), Eu (2)) and polyphosphates NaLn(PO3)4 (Ln = Ce (3), Eu (4)) have been synthesized by the high temperature solution reaction. These compounds have been characterized by means of single-crystal X-ray diffraction, elemental analyses, spectral measurements, and theoretical computations. Their structural characteristics are described, and the

  摘要 通过高温溶液反应合成了稀土二磷酸钠 NaLnP2O7 (Ln = Ce (1), Eu (2)) 和多磷酸盐 NaLn(PO3)4 (Ln = Ce (3), Eu (4))。这些化合物已通过单晶 X 射线衍射、元素分析、光谱测量和理论计算进行了表征。描述了它们的结构特点，并比较了它们之间的差异。根据晶体带结构、态密度 (DOS) 和通过 DFT 方法计算的光学响应函数，对 1 和 3 的化学键的性质和光学跃迁的电子起源进行了分析。光谱测量结果表明，晶体 1 和 3 可能成为发射紫外线的固态光源的有希望的主体，

  A NaCeP2O7 compound was successfully synthesized by a high-temperature reaction with the solid-state method. Analyzing the XRD pattern, of the studied compound, confirms the orthorhombic phase with the Pnma space group. The examination of SEM images reveals that the majority of grains are around 500 to 900 nm with a uniform distribution. As for the EDXS analysis, all chemical elements were detected

  采用固相法高温反应成功合成了NaCeP2O7化合物。分析所研究化合物的 XRD 图证实了具有 Pnma 空间群的正交晶相。SEM 图像检查表明，大部分晶粒在 500 至 900 nm 左右，分布均匀。至于 EDXS 分析，所有化学元素都被检测到并发现了适当的比例。与温度相关的虚数模量 M'' 与角频率的曲线表明在每个温度下都存在一个峰值，证明主要贡献与晶粒有关。使用 Jonscher 定律解释交流电电导率的频率依赖性。从跳跃频率和从模量谱的介电弛豫以及连续电导率中提取的活化能的接近值表明，传输是通过 Na+ 离子跳跃机制发生的。已评估标题化合物中的载流子浓度，表明其与温度无关。指数s随着温度的升高而增加；这种行为证明非重叠小极化子隧穿 (NSPT) 是合适的传导机制模型。指数s随着温度的升高而增加；这种行为证明非重叠小极化子隧穿 (NSPT) 是合适的传导机制模型。指数s随着温度的升高而增加；这种行为证明非重叠小极化子隧穿
