To get good image segmentation results in tomographic analysis methods, particles has to be seperated from each other while embedding them into a matrix. Low X-ray absorbing nano-graphite below the voxel resolution of the system is mixed with the analysis particles to form a shell to avoid direct particle-particle contact. After mixing it with epoxy resin, the paste is sucked into a polymeric tube of 2 mm inner diameter. After hardening, the formed cylinder was scanned with an X-ray microscope (ZEISS Xradia Versa 510) with the following parameters: 80 keV, 7 W, 360°, 2001 projections, 1 s exposure time, 2 µm voxel size, binning 2. After scannning, the following filters were applied while reconstruction with ZEISS reconstructor: Beam Hardening Correction 0.05, Smoothing 0,7. Detailed overview of the parameters is summarized as screenshots within the repository.
