摘要

Acicular particles of Na_0.5Sr_0.25NbO₃ and NaSr₂Nb₅O₁₅ were successfully synthesized in the KSr₂Nb₅O₁₅ + NaCl system and SrCO ₃ + Nb₂O₅ + NaCl + KCl system, respectively. It was found that the anisometric particles could not be obtained in the SrCO ₃ + Nb₂O₅ + NaCl system. A facile ion-exchange approach was utilized to prepare acicular Na_0.5Sr _0.25NbO₃ particles. Acicular NaSr₂Nb ₅O₁₅ particles with large aspect ratio could be obtained at the weight ratio of salt-to-mixture of 5:1, which were ideal template for fabricating textured ceramics. The growth process was researched and the synthesis method was suggested to be a self-precursor templating route. The results will be propitious to guide the fabrication of other templates with anisotropic morphology which were hard to prepare directly.
