Etude à haute temperature du diagramme d'equilibre du système La 2O 3Yb 2O 3
Abstract
The high temperature phase diagram La 2O 3Yb 2O 3 has been studied from 1400°C to the melting point, all together by direct thermal analysis and by X-ray diffraction. Particularly we observe, on the melting point, a cubic solution largely extending from La 2O 3 near to Yb 2O 3. The LaYbO 3 perovskite-type compound which appears below 2040°C, is surrounded by two eutectoïds.
