Facile Preparation of SrZr_1-xTi_xO₃ and SrTi_1-xZr_xO₃ Fine Particles Assisted by Dehydration of Zr⁴⁺ and Ti⁴⁺ Gels under Hydrothermal Conditions.

ABSTRACT: In recent decades, perovskite-type compounds (ABB'O₃) have been exhaustively studied due to their unique ferroelectric properties. In this work, a systematic study aiming to prepare fine particles in the binary system SrZrO₃-SrTiO₃ was conducted under hydrothermal conditions in a KOH (5 M) solution at 200 °C for 4 h under a constant stirring speed of 130 rpm. The precursors employed were SrSO₄ powder (<38 μm size) and coprecipitated hydrous gels of Zr(OH)₄•9.64 H₂O (Zr-gel) and Ti(OH)₄•4.5H₂O (Ti-gel), which were mixed according to the stoichiometry of the SrZr_1-xTi_xO₃ in the compositional range of 0.0 > x > 100.0 mol% Ti⁴⁺. The XRD results revealed the format
