Isothermal section of the Al2O3–TiO2–La2O3 phase diagram at 1400 °C is constructed for first time. It part systematic investigations Al2O3–TiO2–Ln2O3 (Ln = lanthanides, Y) systems. The was taken as temperature, which no liquid expected in system. Samples were prepared by a chemical method. annealed air 80 hour sand cooled furnace. Phases samples determined XRD analysis. New phases and appreciab...

Swaged Mo-xLa2O3 alloys (x = 0, 0.3, and 0.6 wt.%) were subjected to different annealing temperatures (Ta), in order demonstrate the Ta-sensitive La2O3 effect on microstructural evolution tensile ductility. Although coarse particles detrimental ductility, nanosized found increase ductility by highly stabilizing deformation-induced hierarchical microstructures of lamellar elongated grains with l...

Investigations were conducted on a series of calcium and lanthanum oxides catalyst for biodiesel production. Mixed oxides catalyst showed a superior transesterification activity over pure calcium or pure lanthanum oxide catalysts. The catalyst activity was correlated with surface basicity and specific surface areas. The effects of water and free fatty acids (FFA) levels in oil feedstock, water ...
