Thermodynamic consideration of melting of copper based alloys with cerium and neodymium were carried out at 1,623 ∼ 1,773 K and 1,523 ∼ 1,775 K, respectively. Solubilities of cerium and carbon in liquid copper in the presence of C-CeC2 and those of neodymium and carbon in liquid copper in the presence of C-NdC2 were determined: Cerium solubility in liquid copper under C-CeC2 equilibrium was obtained as log (CCe /mass%) = 0.424 + 3.59 × 10-4 T (1,623 ∼ 1,773 K) Neodymium solubility in liquid copper under C-NdC2 equilibrium was obtained as log (CNd /mass%) = 0.492 + 3.15 × 10-4 T (1,523 ∼ 1,775 K) Based on the results of cerium and neodymium solubilities, activity coefficients of cerium and neodymium in liquid copper were calculated: logγCe = -0.035 - 3.81 × 10-4 T - 3.29 × 103/ T (1,623 ∼ 1,773 K) logγNe = -0.638 - 3.15 × 10-4 T - 4.98 × 103/ T (1,523 ∼ 1,775 K)
