The Ce-Sn-Zn alloys were prepared by furnace melting. The isothermal section of the Ce-Sn-Zn system at 400 oC over the whole composition range was established by using X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS). A new ternary compound, CeSn 2 Zn 2 , was discovered in the present work. This compound adopted CaBe 2 Ge 2 structure type (space group P4/nmm) with the lattice parameters of a=0.4455 (9) nm and c=1.0348 (1) nm. The existence of previously known ternary compounds, CeSnZn and Ce 2 SnZn 3 , were confirmed, too. The maximum solubility of Zn in CeSn 3 was determined to be 12.7 at.%. 相似文献
