| Abstract: | Niobium pentaoxide（Nb2O5） and potassium hydroxide（KOH） particles were selected as raw materials,plate-like KNbO3 template precursors for producing plate-like potassium niobate textured ceramics were synthesized by hydrothermal method.By XRD and SEM,crystalline phase and morphology of the particles were analyzed.Effects of hydrothermal reaction conditions and surfactant on preparation of powders were also studied.The results show that suitable plate-like K8Nb6O19.10H2O precursor can be obtained at 140 ℃ for 2 h with 9 mol/L KOH.To add sodium dodecyl-benzenesulfonate（SDBS） can affect morphology of K8Nb6O19.10H2O.The length/thickness ratio of the plate-like powder can increase to 6 after adding sodium dodecyl-benzenesulfonate（SDBS）. |
