“…Understanding the phase relationships of Re-Co-Sb system is helpful for the development of relative materials. The investigations of phase diagrams of the Eu-Co-Sb [5], Gd-Co-Sb [6], Nd-Co-Sb [7] and Pr-Co-Sb [8] have been reported, while no reports have been found on the interaction in the Ce-Co-Sb ternary systems. In this work, we investigated the phase equilibria in the Ce-Co-Sb ternary system at 400 • C.…”
