The Si-SiC porous ceramics derived from the C/C-SiC composites exhibit some of the interesting characteristics over the
conventional porous materials. This paper deals with the analysis of the porous Si-SiC ceramic for open porosity and its
distribution using liquid infiltration techniques like He-gas pycnometer, Archimedes method and mercury intrusion porosimetry.
Further, in order to determine the surface area of the porous Si-SiC ceramics, BET analysis is applied. The frames for modelling are
generated and modelling for open porosity is done based on experimental findings which include an approximation of the open
porosity calculated theoretically from the composite manufacture data, model for estimation of theoretical open porosity and its
distribution. The results obtained from these models are compared with experimental values and hence, the models are validated.
