Synthesis and phase transitions of oxide-ion conducting compound La2Mo2O9 doped with alkaline metals

Low temperature synthesis of hollow La2Mo2O9 spheres by the molten salt solvent method

“…In most cases, lanthanum molybdate compounds are synthesized by solid-state reactions although this method is not suitable for obtaining dense samples. [1][2][3][4][5] Other ways to prepare the La 2 Mo 2 O 9 composition are chemical synthesis methods, including sol-gel, polymeric precursors, combustion of a polyacrylamide gel, freeze-drying of co-precipitated gels, hydrothermal approach and Pechini method, and high-energy milling, etc. [6][7][8][9][10] In comparison with the solid-state reactions, the chemical solution methods can give rise to smaller particles, usually in the nano-size range with enhanced reactivity and chemical homogeneity.…”
