Resumen

Microstructure, piezoelectric properties and dielectric behavior of undoped and MoO3-doped lead-free (K0.44Na0.52Li 0.04)(Nb0.86-xTa0.10-xSb0.04-x) Mo5/6xO3 were investigated. Samples were obtained by the conventional solid state reaction. X-ray diffraction (XRD) and Raman spectra revealed the formation of a perovskite phase, together with some minor secondary phase which could be assigned by XRD to K3LiNb6O 17. XRD also showed that the perovskite evolved from a tetragonal to orthorhombic symmetry with the increased doping level. The temperature dependence on real permittivity revealed the presence of a diffuse phase transition. This behavior raised with MoO3 concentration. Also, dielectric relaxation processes were observed at room temperature resulting dependent on doping level and sintering time.
