High-quality, idiomorphic, single-phase Li5La3Nb 2O12 crystals were successfully grown using a LiOH flux cooling method at the relatively low temperature of 500 C at a solute concentration of 5 mol %. The grown Li5La3Nb 2O12 crystals had polyhedral shapes with well-developed, flat {211} and {110} faces. Their shapes were relatively uniform, and the average crystal size was approximately 59.2 μm. No aggregation was observed in scanning electron microscopy images. The high crystallinity of the Li 5La3Nb2O12 crystals was confirmed by transmission electron microscopy images. Their lattice parameter was determined from the X-ray diffraction pattern to be a = 1.281 nm, which is consistent with the literature value (a = 1.282 nm). Furthermore, the crystal phase, form, size, and crystallinity of the flux-grown Li5La3Nb 2O12 crystals were obviously dependent on the growth conditions including the solute concentration and holding temperature.
