Tomography‐Based Multiscale Analyses of the 3D Geometrical Morphology of Reticulated Porous Ceramics

X‐ray microtomography with a digital resolution of 30 μm and synchrotron submicrometer tomography with a digital resolution of 350/700 nm are performed on catalyst‐coated reticulate porous ceramic foa, 22[2] 121–45ms. Porosity, specific surface, pore‐size distribution, two‐point correlation function, and minimum size of a representative elementary volume are computed by image processing of the tomographic reconstructions on the mm‐scale‐ and μm‐scale‐sized pores. Numerically determined porosities are experimentally validated by weighing, helium pycnometry, and mercury intrusion porosimetry.
