X-ray tomography images of different cellular ceramics have been obtained using appropriate tomography setups.

Abstract

X-ray tomography images of different cellular ceramics have been obtained using appropriate tomography setups. The samples exhibited a wide range of cell sizes (View the MathML source m to mm) but a narrow range of porous fraction (75–85 vol.%). The images have been processed to retrieve the local fraction of ceramic. The average value of this measurement have been compared with a standard method based on image analysis of optical micrographs. The thickness distribution of both pores and ceramics was also retrieved using three-dimensional (3D) mathematical morphological operation on the images. The average value of these granulometry measurements was compared to optical and electron microscopy measurements.
