reconstructed CT data of filter cakes Löwer, Erik CT data of two filter cakes, built from glass beads (B70) and quartz sand (BCS201) in an in-situ pressure nutsch according german guideline VDI 2762-2. The soda-lime glass beads (density 2.55 g/cm³, 72.30 m.-% SiO2, 13.30 m.- % Na2O, 8.90 m.-% CaO and 4.00 m.-% MgO) of the size of 70 < x < 110 μm were purchased from Sigmund Lindner GmbH, Germany, and are manufactured via dry spraying. The quartz sand (density 2.65 g/cm³, 99.1 m.-% SiO2 with traces of Fe2O3, Al2O3 and TiO2 with < 0.3 m.-%) was purchased from Strobel quartzsand GmbH, Germany, in the fraction x < 200 μm, coming from a comminution process. For the filtration experiments, the solids are suspended in an aqueous solution of de-ionized water, potassium iodide (25 mM) and glycerol (24 m-%), resulting in a density of 1.10 g/cm². After filtration until gas breakthrough, the filter cakes are measured tomographically (ZEISS Xradia 510 Versa). field of view: 4 x 4 cm², sample size: 5 x 5 x 12.9 mm³ (B70)/5 x 5 x 12.4 mm³ (BCS201), source filter (ZEISS standard): LE5 (B70)/LE4 (BCS201), acceleration voltage / power: 50 kV/4 W, optical magnification: 4x, pixel size: 4.00 μm (B70)/3.98 µm (BCS201), exposure time 8 s (B70)/4 s (BCS201), projections: 2001 @360°, camera binning: 2
