https://opara.zih.tu-dresden.de/xmlui/handle/123456789/5692 The 3D particle analysis offers the possibility to capture several particle characteristics simultaneously. However, when using X-ray tomography over several size scales (nano- and micro CT), it is not possible to derive quantitative information about the material composition of samples directly from the image grey values. Within the project, this is to be done by correlating the 3D volume with 2D elemental analysis (EDXS) utilizing a FIB-SEM workflow. 2026-04-12T01:06:41Z https://opara.zih.tu-dresden.de/xmlui/handle/123456789/5733 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"). 2022-01-01T00:00:00Z
