20、ngsha 410083, China) Abstract: The principle and measurement method for graphitization degree of carbon materials by X -ray diffraction were investigated, through calculating the lattice constant c value of hexagonal system graphite precisely. So it was very neces - sary to correct measure error...
X-ray diffraction (XRD) profiles of these chars showed that the metal species in the char existed as an oxide or elemental metal or carbide, depending on the heat-treatment temperature. The thermodynamic feasibility of formation of the metal via the reduction of the oxide by carbon (char) ...

CARBONATE IDENTIFICATION USING X-RAY DIFFRACTION (XRD) AND CARBON AND OXYGEN ISOTOPE CHEMOSTRATIGRAPHY OF THE RUBY RANCH MEMBER WITHIN THE CEDAR MOUNTAIN FORMATION (South-Central Section - 47th Annual Meeting (4-5 April 2013))MONTGOMERY, Elizabeth H...
This study attempts to solve the 3D structure of graphitic carbon nitride by means of X-ray diffraction and of neutron scattering. Initially, various structural models are considered and their XRD patterns compared to the measured one. After selecting possible candidates as g-C3N4 structure, neutron...
The structural changes of graphite-mixed and carbon-coated silicon, used as lithium intercalation materials, have been studied during discharge–charge using synchrotron-based in situ X-ray diffraction. The lithium intercalation (de-intercalation) takes place in the graphite first during discharge (charg...
The role of carbon dioxide in the formation of thaumasite Detailed analyses of the nature of the thaumasite-ettringite solid solutions that formed have been carried out, and the mechanism of thaumasite formation, ... G Collett,NJ Crammond,RN Swamy,... - 《Cement & Concrete Research》 被引量...
The XRD data proved a dominant 3C-SiC structure accompanied by an admixture of the residual 6H-SiC phase. The main core-level photoelectron spectra were analysed in detail. In particular, the C 1s level spectrum revealed a three peaks structure containing the peak indicative of free carbon as ...
