Etude a haute température des systèmes formes par le sesquioxyde de lanthane et les sesquioxydes de lanthanides. I. Diagrammes de phases (1400°C < T < T Liquide)
Abstract
Studies involving thermal and X-ray diffraction analyses have been carried out at high temperature on the systems La 2O 3 Ln2O 3 ( Ln = lanthanon element). Homogeneity and thermal stability of the cubic (Tl 2O 3 form), monoclinic (Sm 2O 3) form, hexagonal A or H (La 2O 3 form) and cubic X solutions have been examined. Tentative equilibrium diagrams have been drawn from 1400°C through the liquid state.
