The system La2O3WO3, especially the La2O3-rich portion was studied by a thermal analysis, high temperature X-ray diffraction, annealing of fused samples, solid state reaction and DTA methods up to the liquidus. Eight intermediate phases, La2O3:WO3 = 3:1, 5:2, 3:2, 1:1, 7:8, 1:2, 1:3 and 2:9, were found and characterized. In addition, two unquenchable solid solution phases based upon La2O3X and H, have been found. A phase diagram is presented.
