|---|---|---|---|
| 8.411 | 50. | Thermodynamics Research Center, 1997 | p=1 bar. Selected values agree with results of statistical calculation [ Compton D.A.C., 1977] within 0.1-1.4 J/mol*K. Thermodynamic functions calculated by [ Anjaneyulu Y., 1988] are larger than selected ones at high temperatures (up to 6.6 J/mol*K in S(1500 K) and 2.8 J/mol*K in Cp(1500 K)). |
