General purpose diffractometer for powders and thin films equipped with a solid state RTMS ultrafast detector. High temperature reaction chamber available for measurements at controlled temperatures and with controlled atmosphere.
In the present work we report the full structural and spectroscopic characterization of an UICC crocidolite standard sample, that is a fibrous riebeckite from Koegas Mine, Northern Cape (South Africa). The chemical composition was obtained by SEM-EDS and cation site partition was retrieved by complementing chemical, Mössbauer and X-ray powder diffraction data. Cell parameters, fractional coordinates, and site scattering for M(1), M(2), M(3), M(4) were refined using the Rietveld method.
