- Аннотация: Pure and sodium-containing lanthanum oxymolybdates were synthesized as polycrystalline samples and single crystals. The compounds have been characterized by several methods including SEM, inductively coupled plasma MS, X-ray single crystal diffraction analysis, thermogravimetry, differential scanning calorimetry, IR-spectroscopy, and impedance spectroscopy. ICP-MS has shown the presence of sodium cations in single crystals. According to X-ray diffraction analysis, sodium cations replace lanthanum atoms in the structure. The I4̅c2 (Z = 8) space group was established for sodium-containing crystals. The feature of Na-doped polycrystalline La2MoO6 samples is a reversible phase transition at about 650 °C recorded by DSC. La2MoO6 ceramics with sodium absorb water as evidenced by TG and IR-spectroscopy data. Investigated materials exhibit proton conductivity in a humid environment.
