The value of the osmium melting heat, ΔHm= 57.85 kJ/mol, presented in reference handbooks was obtained about 35 years ago from a wide extrapolation (in temperature) of experimental data on the melting entropy of the FCC and the HCP elements of the Periodic Table. Using the correlation of data on the surface tension (developed by B. D. Summ), the melting heat, and the surface layer structure for osmium, the authors obtain a new estimate, ΔHm = 30−40 kJ/mol, which is half of the reference value.
