摘要：
Thermodynamic evaluation of Cu-Cu3P system has been conducted by applying subregular solution model with Gibbs energy of CUR formation that was newly determined by means of triple Knudsen cell mass spectrometry. Both the calculated vapor pressure of phosphorus and phase diagram of Cu-P system are excellently consistent with the literature data in the composition range of Cu-Cu3P, indicating that there is no significant thermodynamic inconsistency between the present work based on the Gibbs energy of Cu3P formation determined and the literature data.
