Abstract

This work reviews and discusses the data and information on the various thermodynamic properties of vanadium available through March 1985. These include the heat capacity and enthalpy, enthalpy of melting, vapor pressure, and enthalpy of vaporization. The existing data have been critically evaluated and analyzed, and the recommended values for heat capacity, enthalpy, entropy, and Gibbs energy function covering the temperature range from 1 to 3800 K have been generated. These values are referred to temperatures based on IPTS-1968. The units used for various properties are joules per mole (J Ā· molāˆ’1). The estimated uncertainties in the heat capacity are Ā±3% below 15 K, Ā±10% from 15 to 150 K, Ā±3% from 150 to 298.15 K, Ā±2% from 298.15 to 1000 K, Ā±3% from 1000 to the melting point (2202 K), and Ā±5% in the liquid region.
