英文摘要	借助于DTA与X射线衍射法研究了YbCl3-MCln（M=Li、Mg、Ca、Pb;n=1或2）二元体系相图．发现YbCl3-LiCl体系相图属固液异组成型，有化合物Li3YbCl6生成，它在481℃有一相转变.其无变点分别为xYbCls＝0．410；526℃和xYbCl3=0.340，547℃；YbCl3-MgCl2属类转熔型相图，在富YbCl3相区666℃有一尚不知其性质的热效应，为xYbCl3＝0．380，628℃；YbCl3－CaCl2和YbCl3-PbCl2体系皆属简单低共熔型相图，其低共溶点分别为xYbCl3＝0．530,615℃和xYbCl3＝0．340,415℃.后者在固相下有一...; The Phase diagrams of binary systems YbCl3-MCln (M=Li, Mg, Ca, Pb; n=1 or 2) were investigated by means of DTA and X-ray diffraction analysis. It was found that YbCl3-LiCl system is of peritectic type with compound Li3YbCl6 and its phase transition is at 481 degrees C as well as the invariant points E (x(YbCl3)=0.410, 526 degrees C) and P (x(YbCl3)=0.340, 547 degrees C) YbCl3-MgCl2 system is of peritectic-like type with a peritectic-like line over the YbCl3-rich region at 666 degrees C and the peritectic compound could not be specified. Its eutectic point e is (x(YbCl2)=0.380, 628 degrees C). YbCl3-CaCl2 and YbCl3-PbCl2 systems are of simple eutectic type with eutectic points (x(YbCl3)=0.530, 615 degrees C) and (x(YbCl3)=0.340, 416 degrees C) respectively. An unstable compound, formed in the solid state, is PbYbCl5 and decomposes at 392 degrees C. Some rules of the phase diagram were also explored.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000207589100011&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 4; 04; 342-347; 10
