Thermodynamic Properties of Iron and Silicon
Abstract
This work reviews and discusses the data on the various thermodynamic properties of iron and silicon available through March 1984. These include heat capacity, enthalpy, enthalpies of transition and melting, vapor pressure, and enthalpy of vaporization. The recommended values for heat capacity, enthalpy, entropy, and Gibbs energy function cover the temperature range from 1 to 3200 K for iron and 1 to 3600 K for silicon. The recommended values for vapor pressure cover the temperature range from 298.15 to 3200 K for iron and from 298.15 to 3600 K for silicon. These values are referred to temperatures based on the International Practical Temperature Scale of 1968. The energy units used are joules per mol (J mol−1). The uncertainties in the recommended values of the heat capacity range from ±1.5% to ±5%.

At temperatures of 311 and 417 K, population effects are less critical because the heat capacity is at 75 and 83% of saturation, respectively.

At temperatures of 81 and 155 K, the heat capacity is at 20 and 45% of saturation, respectively; high-frequency phonon modes are not populated, and phonon-phonon scattering is reduced relative to 311 K.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
