Viscosity-dependent hydrothermal synthesis of multinary titanate perovskites.

ABSTRACT: An innovative viscosity-dependent hydrothermal strategy is developed for the controlled synthesis of multinary titanate perovskites, specifically Na_0.5Y_0.39Yb_0.1Er_0.01TiO₃. By manipulating the viscosity of the reaction solution using various stable additives in both type and quantity, we identify a critical viscosity threshold of ~100 centipoise, which is essential for producing uniform faceted particles. With sodium hydroxide as an additive, a clear morphological evolution occurs as hydroxide concentration increases, shifting from regular cubes to edge-truncated, half-corner-truncated, and fully corner-truncated cube particles. Furthermore, the inclusion of additional sodium chloride and acetate substantially increases the viscosity,
