摘要
Based on the analysis and evaluation of the thermodynamic information (including heat capacity, enthalpy, entropy, relative magnetic parameter, solid transition temperature, melting point, solid transition enthalpy and melting enthalpy, etc.) on all the condensed phases (hcp-, bcc-Dy and the liquid Dy), a description of the Gibbs energy of various condensed phases of dysprosium at 101325 Pa was obtained for the whole temperature range of 100-3000K. The magnetic contribution of the Gibbs energy of hcp-Dy was described by using the Inden-Hillert-Jarl phenomenological model. The data of different measurable thermodynamic properties of hcp-, bcc-Dy and the liquid Dy, were calculated by using the above description of the Gibbs energy, which reproduce very well the experimental data from different sources.
