Reinvestigation of the Ce–Co–Al ternary system: Isothermal section at 973 K

Abstract : The Ce–Co–Al ternary phase diagram has been reinvestigated at 973 K by means of powder X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy and differential thermal analyses. It contains 5 ternary phases (CeCo2Al8, Ce2Co6Al19, CeCoAl4, Ce3Co3Al4 and CeCoAl) as well as 7 extensions in the ternary field of pseudo-binaries (CeAl2−xCox with 0 ⩽ x ⩽ 0.18; CeCo2−xAlx with 0 ⩽ x ⩽ 0.21; CeCo3−yAly with 0 ⩽ y ⩽ 0.20; Ce2Co7−xAlx with 0 ⩽ x ⩽ 0.73; Ce5Co19−yAly with 0 ⩽ y ⩽ 0.20; CeCo5−xAlx with 0 ⩽ x ⩽ 0.71 and Ce2Co17−yAly with 0 ⩽ y ⩽ 2.2). Two liquid areas are present at the Al and Ce-rich corners of this isothermal section
