The phase diagram of the Ba-Ge system has been revised, in the composition range 0-75 at.% Ge, from a thermal point of view, resulting substantially different from that previously reported in Massalski collection. The existence and composition of the following compounds are confirmed: Ba2Ge, Ba5Ge3, BaGe, dimorphic Ba3Ge4, BaGC2, Ba6Ge25 and Ba8Ge43. Save for Ba2Ge, BaGe and BaGe2, forming congruently, all other phases melt incongruently. Four eutectic points occur at 7.5, 42.5, 56.0 and 82.5 at.% Ge, respectively. (c) 2007 Elsevier B.V.

The phase diagram of the Ba-Ge system

Abstract
The phase diagram of the Ba-Ge system has been revised, in the composition range 0-75 at.% Ge, from a thermal point of view, resulting substantially different from that previously reported in Massalski collection. The existence and composition of the following compounds are confirmed: Ba2Ge, Ba5Ge3, BaGe, dimorphic Ba3Ge4, BaGC2, Ba6Ge25 and Ba8Ge43. Save for Ba2Ge, BaGe and BaGe2, forming congruently, all other phases melt incongruently. Four eutectic points occur at 7.5, 42.5, 56.0 and 82.5 at.% Ge, respectively. (c) 2007 Elsevier B.V.
