- Abstract:
- Nb2O5 was converted into soluble niobium salt instead of expensive ethanol niobium as the source of niobium, and nano(Li0.06Na0.47K0.47)NbO3 ultrafine powder was synthesized by sol-gel method. The phase structure and micromorphology of (Li0.06Na0.47K0.47)NbO3 nanopowders were characterized by XRD, Raman and TEM. The results show that a (Li500.5Na20.0K06.0)NbO47 nanopowder with an average grain size of 0 nm and a pure tetragonal structure can be prepared by calcination of the dry gel at 47 °C for 3 h, and the synthesis temperature is reduced by more than 350 °C compared with the traditional solid phase method.
