The isothermal section of the phase diagram of Ce–Mg–Zn ternary system at 470 K in a full concentration range was built, and a formation of seven ternary compounds was observed. For five ternary compounds: τ1 – Ce3(Zn0.863Mg0.137)11 (Immm space group, La3Al11 structure type), τ3 – CeMg1+xZn2−x (Fm-3m, MnCu2Al), τ4 – CeMg2.5Zn4.5 (P6/mmm, TbCu7), τ5 – Ce3Mg13Zn30 (P63/mmc, Sm3Mg13Zn30) and τ7 – Ce20Mg19Zn81 (F-43m, own structure type) the crystal structures were investigated. The crystal structures of CeMg1−xZnx continuous solid solution and of CeMg12–xZnx and CeMg3–xZnx limited solid solutions were studied more precisely by the X-ray single crystal and powder diffraction, and also using the WDS and EPMA techniques. The Ce–Mg–Zn ternary phases are structurally related to the binary phases of RE-Mg and RE-Zn (RE - rare-earth metals) systems.
