Abstract
Abstract This paper reports the rapid synthesis of perovskite (ATiO 3 , A = Ca, Sr, Ba) via molten salt method within 10 min BaCl 2 or CaCl 2 was used due to their excellent solubility of O 2− which enables faster mass transfer transport in the liquid phase. TiO 2 , ACl 2 and CaO (or BaCO 3 ) were used as the precursors. The obtained ATiO 3 show high chemical and phase purity. Studies found that cation size in ATiO 3 plays an important role in the transformation between different perovskites. The method may provide a generalized methodology for rapid preparation of other important perovskites.
