Strength parameters of isotropic high-density graphite are thought to be strongly correlated to pore structure of the graphite from experimental results on fracture toughness. In this paper, we present quantitative analysis of pore structure in the isotropic graphites by means of an image processing of a polarizing microscope image of the material. Power spectra of the polarizing microscopic images of the isotropic graphite are obtained by the 2-dimensional fast Fourier transform. These results indicate that the structure of the pores and the other solid parts of the graphite are almost isotropic. Distribution of the area, the number, the circularity, and the fractal dimension of cross-section of the pores are measured, and the pore structure is analyzed quantitatively.
