The increased use of graphites has led to the requirements for a graphitic thermal conductivity and diffusivity standard. Candidate graphites were screened on the basis of criteria such as reproducibility, isotropy, availability, and heating test results. Samples of two selected graphites -AXM-5Ql a
The porosities of a number of graphites were determined by mercury porosimetry and helium intrusion methods, and in addition, vapor pressures and mercury distillation data were obtained on graphite specimens intruded with mercury in a porosimeter. All of the results were in agreement with the conclu
