Thermal and physical properties of a series of porous, polycrystalline graphites have been measured. The solid matrix material was characterized by X‐ray diffraction measurements of crystallite size, interplanar spacing, and anisotropy. The pore structure was examined using electron micrography, porosimetry, permeability, and helium density measurements. Thermal and electrical conductivities and elastic modulus measurement results were correlated with the fractional porosities of the graphites.
