Abstract : This report presents the results of an investigation into the mass loss rate from a pyrolytic graphite foil at various temperatures and pressures. The mass loss in a hydrogen atmosphere is presented at temperatures from 3000 to 4100 R and pressures from 830 to 1550 Torr. The mass loss rate in an inert helium atmosphere at the same temperatures and at pressures from 0.001 to 1550 Torr is presented. The experimental data is compared to the theoretical rate and, when applicable, to the work of previous experimenters.
