Abstract

The nanocrystalline sodium niobate(NaNbO₃) and sodium tantalite(NaTaO₃) powders with perovskite structure were synthesized by the solvthermal method with glycol as solvent. These powders were characterized by powder X-ray diffraction(XRD), Raman spectroscopy, Scanning electron microscopy (SEM) and transmission electron microscopy(TEM). Rietveld refinement of X-ray diffraction data and Raman spectroscopy confirm that the nanoparticles of NaNbO₃ and NaTaO₃ have orthorhombically distrorted structures with Pmc2₁ and Pbnm space groups, respectively. The SEM photograph shows that NaTaO₃ and NaTaO₃ powder are cubic morphology. The TEM and the SAED pattern confirmed that the nanoscale NaTaO₃ is single-crystal structure. In addition, the influence of the concentration on the NaTaO₃ powder characteristics was also detailed investigated.
