In the present work, effects of different salts (NaCl, 0.5NaCl-0.5KCl and KCl) on molten-salt-synthesized Sr0.5Ba0.5Nb2O6 (SBN50) powder were explored. A variety of particle morphology, compositions and lattice parameters of SBN50 were investigated. The results showed that SBN50 particles synthesized in NaCl salt have the finest diameter (0.1-0.2μm) and the highest aspect ratio (around 10), while the particles from 0.5NaCl-0.5KCl salt show the coarsest diameter (0.2-0.3μm) and the lowest aspect ratio (around 5). If only using KCl salt, trace Sr2Nb2O7 normally co-exists with SBN50 phase. In addition, Na+ and K+ cations from salts are easily incorporated with SBN structure and reach a very high content.
