Description

Study of MoO3-UO2MoO4-Na2MoO4 diagram puts in a prominent two new-phases: G: Na2U3Mo9O37, incongruently melting point and H: Na2UMo4O16, congruently melting point. The results only can interpret within the context of MoO3-UO3-Na2O ternary system. They lead to the existence of new three-phase fields within MoO3-UO3-Na2O ternary system. They lead to the existence of new three-phase fields within MoO3-UO2MoO4-E = Na2UO2(MoO4)2 - Na2Mo2O7 quadrilateral. Combining our previous works with this paper, we give the general appearance of ternary liquidus and cristallisation fields of several compounds

Abstract (French)

L'etude du diagramme MoO3-UO2MoO4-Na2MoO4 met en evidence deux nouvelles phases: G: Na2U3Mo9O37, a fusion non congruente et H: Na2UMo4O16, a fusion congruente. L'interpretation des resultats necessite le cadre complet du systeme UO3-MoO3-Na2O et conduit a l'existence de huit nouveaux domaines triphases solides dans le quadrilatere limite par MoO3-UO2MoO4-E = Na2UO2(MoO4)2 et Na2Mo2O7. En associant nos travaux anterieurs avec ceux de ce memoire, nous donnons l'allure generale du liquidus ternaire et des domaines de cristalisation des divers composes
