Abstract

Perovskite-type (A,La)TiO₃ (A: Li or Na) nanoplates were synthesized by hydrothermal reaction using titanium bis(ammonium lactate) dihydroxide as a starting material at 260 °C for 48 h. When NaOH was used as a mineralizer, perovskite single phase was obtained, but when LiOH was used, impurities including lanthanum hydroxide were obtained, and no perovskite phase was obtained. Scanning transmission electron microscopy (STEM) analyses demonstrated that perovskite NPs have plate-like morphology with plane index of {100}. Energy dispersive X-ray spectroscopy (EDX) revealed that Na partly occupied in A-site of perovskite structure. The nanoplates were pressed into a pellet and sintered at 1000 °C. The pellet exhibited an ionic conductivity of 3.8 × 10⁻⁶ S/cm. [Figure not available: see fulltext.]
