Abstract

New vapor pressure data for cobalt have been obtained in the temperature range 1519–1926°K from Knudsen effusion experiments. The derived third-law heat of vaporization of cobalt is Δ H298°=101.0± 0.6 kcal/mole. Plausible explanations are presented that account for the widely differing vapor pressure data and heats of sublimation published in the literature. It is shown that the evaporation coefficient for cobalt is essentially unity rather than 3×10−4 and that the electron impact ionization cross section for cobalt is σ (Co=4.4± 1× 10−16 cm2 for 50 eV electrons.
