WebApr 1, 2014 · The atomic structure of several nuclear graphite samples, an essential moderator material for nuclear reactors, has been investigated by X-ray diffraction. The patterns were analyzed by the conventional Rietveld refinement approach as well as by the CARBONXS model, which takes into account disorder and stacking faults. WebJul 15, 2009 · The collected diffraction patterns exhibit intense broadening of several of the reflections, characteristic of turbostratic stacking. In order to quantify this disorder structurally, a model combined with a Rietveld-like refinement approach was implemented, which includes several refinable parameters that aim at describing this type of structure.
WebMay 9, 2014 · Rietveld Refinement. In Rietveld refinement, as described by Young [1], the powder pattern is calculated according to the following equation: yci = SΣKLK FK 2φ (2θi - 2θK)PKA + ybi. where. yci is calculated intensity at point i. K represents index (hkl) of Bragg reflections contributing to intensity at point i. S is phase scale factor. WebCrystallography is the experimental science of determining the arrangement of atoms in crystalline solids.Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics).The word crystallography is derived from the Ancient Greek word κρύσταλλος (krústallos; "clear ice, rock-crystal"), with its …
