用X射线衍射、扫描电镜和能谱仪测定了Ag-La-Sn三元系在400°C时的相平衡。在该体系中发现了一种新的三元化合物AgLa_5Sn_3。该化合物属于Ti_5Ga_4结构类型，晶胞参数a=0.96827（6），c=0.68747（7）nm。La_2Sn_5为Ce_2Sn_5型结构，a=0.46224（5），B=3.5702（5），c=0.46847（5）nm。
The phase equilibria in the Ag–La–Sn ternary system at 400°C were determined by means of X-ray diffraction, scanning electron microscopy and energy dispersive spectrometer. A new ternary compound AgLa5Sn3was discovered in the system. This compound crystallized in Ti5Ga4structural type with cell parameters of a=0.96827 (6) and c=0.68747 (7)nm. La2Sn5was confirmed to adopt the Ce2Sn5-type structure with a=0.46224 (5), b=3.5702 (5) and c=0.46847 (5)nm.
