Saxolite and Talcum are two materials with comparable X-ray attenuating properties and thus not to distinguish by direct comparison of image gray values. https://opara.zih.tu-dresden.de/xmlui/handle/123456789/5693 2026-04-07T03:35:46Z 2026-04-07T03:35:46Z Ditscherlein, Ralf https://opara.zih.tu-dresden.de/xmlui/handle/123456789/5733 2022-09-02T12:03:17Z 2022-01-01T00:00:00Z

3 tomographic data sets of nano-CT measurements of a 30:70 vol-% mixture of talcum and saxolite Ditscherlein, Ralf All 3 data sets are sub-volumes (Field of View approx. 65 µm) of a total sample of a particle mixture of talc and saxolite fixed in a matrix by means of epoxy resin and spacer particles (nanometre-sized carbon black particles, 150 nm equivalent spherical diameter). The primary analysis was carried out using nano-CT. The reconstructed result data are stored in the form of TIF files as sectional images (folder "rotated"). In addition, a correlation was carried out by means of EDXS analytics, the chemical information of which was used to train a segmentation algorithm. Since EDXS analysis requires a planar surface, the sample was further processed using FIB. The divergence of the ion beam produces a slight angular deviation from the perpendicular of the nano-CT volume, which necessitated a rotation of the initial volume data (--> "rotated"). The correlated result data of the particle-discrete phase information are also stored ("rotated segmented").
