Er-Se (Erbium-Selenium) Editor Two Er-Se phase diagrams were presented by the same authors, [65Haa1] and [ 65Haa2]. These diagrams are similar, but invariant temperatures in [65Haa1] are higher by up to 120 C. The assessed phase diagram is primarily redrawn from [65Haa2], which was published later and presumably superseded [65Haa1]. The Er-rich eutectic composition, however, is adopted from [65Haa1], because the initial slope calculation with the van't Hoff relationship indicates that the eutectic composition of "3 at.% Se" in [65Haa2] is very unlikely. According to [65Haa2], Er3Se4 and Er2Se3 form a solid solution range. This range is shown as a single-phase field in the assessed diagram.-H.O. 61Bru: G. Bruzzone, Atti Accad. Naz. Lincei, Rend. Cl.
