An isothermal section of the diagram of the state of the La2O3-Lu2O3-Yb2O3 system at 1500 C. was constructed. of ordered perovskite-type phases LaLuO3 and LaYbO3 (R). No new phases were detected. It is established that a continuous series of solid solutions is formed in the La2O3-Lu2O3-Yb2O3 system at 1500 C on the basis of ordered phases of the perovskite type. A fairly wide area of ??homogeneity of these solid solutions allows the choice of compositions in a wide concentration range for optically transparent materials. On the basis of the obtained data, the optimal composition for the synthesis of nanomaterials for the production of optically transparent ceramics based on the ordered phase of LaLnO3 perovskite type was selected in relation to the structure of an isothermal cross section of a system diagram based on lanthanum, lutetium and ytterbium oxides Product Description popup.authors Bykov Oleksandr I.
