本文通过X射线衍射实验证实了CePd5化合物的结构, 进一步研究了含50-100at%Pd的Ce-Pd系相图, 在750℃以上含50-100at%Pd的Ce-Pd系相图中共有5个中间化合物:CePd5, CePd3, Ce2Pd3, Ce3Pd4和CePd。

The phase diagram of Ce-Pd alloys containing 50-100 atomic% Pd at ?50?was studied. Intermetallic compounds CePd5, CePd3, Ce2Pd3, Ce3Pd4, and CePd were formed. Eutectic reactions Pd + CePd5 J L, CePd3 + Ce2Pd3 J L, and Ce3Pd4 + CePd J L, and peritectic reactions CePd3 + L J CePd5 and Ce3Pd4 + L J Ce2Pd3 were observed CePd2 had a CaCu5-type structure, CePd3 had a AuCu3-type structure, and CePd had CrB-type structure < 958?
