Analysis of Rietveld Method Application for Gyrolite Crystal Structure Refinement

Materials Science, 2012
The several simulated X-ray diffraction patterns for calcium silicate hydrate – gyrolite were calculated with GSAS program using the structural model of natural mineral gyrolite and profile parameters values determined from refining crystal structure of real synthetic gyrolite.

An insight into the thermal properties of struvite-k by Rietveld refinement method

Journal of Materials Research and Technology, 2023
This work investigated the thermal properties of struvite-k (a main binding phase and a strength-giving mineral from the magnesium potassium phosphate cements) exposed to different conditions by Rietveld Refinement Method coupled with X-ray diffraction analysis (XRD) identification, thermogravimetry/differential scanning calorimetry (TG/DSC) and ...

Refinement of monoclinic ReO2 structure from XRD by Rietveld method [PDF]

Brazilian Journal of Physics, 2004
ReO2 presents two crystalline variants, with monoclinic and orthorhombic structures. The former is metastable and irreversibly transforms to an orthorhombic structure above 460 o C. The structure of the latter was determined from studies on monocrystalline samples, whereas for the monoclinic variant there are no single crystals available so far. It was

Rapid Analysis of Feldspar by X-ray Diffractometry Rietveld Refinement Method

Yankuang ceshi, 2017
The content of minerals in feldspar can be calculated by chemical analytical results, but the analytical process is long and the calculation process is complex. Moreover, slice position could affect the result of feldspar content determined by optical microscopy.
