چکیده انگلیسی
The acicular Sr0.39Ba0.48K0.32Nb2O6 single crystal particles were first prepared by the reaction of SrCO3, BaCO3 and Nb2O5 in molten K2SO4 at 1300 °C for 3 h. By using these single crystal particles as seeds and V2O5 as additives, textured Sr0.4Ba0.6Nb2O6 (SBN40) ceramics were obtained. The effect of V2O5 on sintering behaviour, microstructure and dielectric properties of textured SBN40 ceramics was investigated. The experimental results show that the addition of V2O5 can accelerate the densification rate of the material and encourage the texture of SBN40 ceramics, which further improves the anisotropy in dielectric properties between different directions of textured SBN40 ceramics.
