The phase composition and microstructure of MnO-doped MP2O7 is studied with X-ray diffraction (XRD) and scanning electron microscopy (SEM) and the ionic conductivity of the sintered sample is ...

2016年9月1日 · The crystal structures of different powders were analysed using X-ray diffraction (XRD, X’Pert PROMPD), with a scan range of 5–80° over 2 h. The morphologies of the CeP 2 O 7 /BPO 4 membranes were investigated via a SU-8020 Scanning Electron Microscope.

CeP2O7 crystallizes in the cubic Pa-3 space group. The structure is three-dimensional. Ce4+ is bonded to six equivalent O2- atoms to form CeO6 octahedra that share corners with six equivalent PO4 tetrahedra.

2008年9月15日 · The powder synthesis process was monitored by TG-DSC (NETZSCH STA 409 PC) with a heating of 5 °C/min. X-ray diffraction (XRD) analysis (D/max 2550 V) was performed with Cu Kα source to determine the phases. The final Ce/P molar ratio of the compounds was confirmed to be 2.0 ± 0.02 by X-ray fluorescence (XRF) measurements (Philips PW2404 ...

2014年10月1日 · X–ray diffraction (XRD) was measured with a PANalytical X'Pert Pro MPD diffractometer with Ni filter using Cu K α radiation (λ = 0.15418 nm). The micrograph of the Ce 0.95 Yb 0.05 P 2 O 7 sample was taken by a scanning electron microscope (SEM).

2024年12月30日 · Analysis of the samples surface morphology with X-ray diffraction revealed sharp peaks of RDP at specific angles, and the doped CeP2O7 exhibited corresponding XRD angles. Field emission scanning electron microscopy (FESEM) images showed distinct outlines and consistent sizes for the RDP and CeP2O7 particles, with no visible grain or grain ...

XRD pattern of CeP2O7 powders (a) as-prepared, (b) calcined in air at 200 C, (c) calcined in air at 250 C, and (d) calcined in air at 300 C.

2018年4月22日 · ZrP2O7-CeP2O7 solid solutions, Zr1-xCexP2O7; x = 0–0.2 and (Zr0.92Y0.08)1-yCeyP2O7; y = 0–0.1, were prepared by partially replacing Zr4+ with Ce4+ and its effect on the phase composition, sintering behavior, microstructure, and ionic conductivity is analyzed.

2012年10月5日 · The composite was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS).

2019年7月1日 · 通过热重分析/差热分析 (tga/dta)、差示扫描量热法 (dsc) 和 x 射线衍射 (xrd) 研究材料的相发展，并通过扫描电子显微镜分析粉末和烧结试样的微观结构(sem) 和高分辨率透射电子显微镜 (hr-tem)。
