The effect of TiO2 addition on microstructure and dielectric characteristics of tungsten bronze structured K 6 Li 4 Nb 10 O 30 (KLN) and Ba 2 Na 1 Nb 5 O 15 (BNN) was examined. Solid solution limits of TiO2 in KLN and BNN are thought to be around 0.5 and 0.4 mol, respectively. As the amount of TiO2 increased, lattice constants of KLN and BNN decreased. Microstructure of BNN was sensitively influenced by TiO2 addition, which was explained by the generation of vacancies. TiO2 addition was effective in decreasing the phase transformation temperature of KLN, while it was effective in suppressing the dielectric curve of BNN at the phase transformation temperature.
