OF FORMATION OF THE SOLID SOLUTIONS OF ZINC, GALLIUM AND GERMANIUM IN COPPER* 0. J. KLEPPA'f and R. C. KING? The heats of formation of the solid solutions of zinc, gallium and germanium in copper have been determined by liquid tin solution calorimetry. The results for copper-zinc and copper-gallium are consistent with the predictions of the Friedel theory of metallic solutions. CHALEURS DE FORMATION DES SOLUTIONS SOLIDES DU ZINC, GALLIUM ET GERMANIUM DANS LE CUIVRE Les chaleurs de formation des solut,ions solides du zinc, gallium et germanium dans le cuivre sont d&termin&es par calorim&rie de solution dans l'&ain liquide. Les resultats pour les alliages cuivre-zinc et cuivre-gallium sont en accord avecc la th&xie de Friedel sur les solutions m&alliques. BILDUNGSWARMEN VON FESTEN LOSUNGEN VON ZIKK, GALLIUM UND GERMANIUM IN KUPFER Die Bildungswtirmen der festen LGsungen van Zink, Gallium und Germanium in Kupfer wurden kalorimetrisch in fliissigem Zinn bestimmt. Die Ergebnisse fiir Kupfer-Zink und Kupfer-Gallium sind mit den Vohersagen der Friedelschen Theorie metallischer LGsungen vertriiglich.
