Abstract

The microstructures of MiCa-SiC ceramics depend on the pore morphology of their carbon preforms. It is possible to adapt MiCa-SiC to diverse industrial applications by regulating the material phases and properties. The pore network of the considered material can be characterized efficiently by combination of high resolution computed tomography. Two different methods are used for the determination of a Pore Size Distribution (PSD): spherical granulometry and discrete PSD by cells reconstruction. The PSD from both methods show a certain similarity. Furthermore, a procedure for the determination of a Representative Unit Cell (RUC) is presented. Adequate morphological and topological parameters for carbon preforms of MiCa-SiC ceramics are selected and calculated from CT data. Their variation in function of the size of the CT volume is investigated.
