Y and V codoped SrBi ₂Nb ₂O ₉ ceramics, which have been characterized by XRD, FTIR and SEM techniques, were prepared through molten salt using NaCl-KCl medium. Through X-ray diffraction analysis, all prepared samples were matched by undoped SrBi ₂Nb ₂O ₉. The lattice parameters do not depend on the amount of dopants. Under the optimized experimental conditions, the compounds are composed of small crystallites of varying size and orientation, resulting in many micros train defects. FTIR spectra revealed that the dopant promotes a slight decrease in the 612 cm ^–1 band. A plate-like morphology was revealed by scanning electron microscopy, while Nyquist plots indicate non-Debye relaxation for all compounds. V and Y were incorporated into SrBi ₂Nb ₂O ₉ lattice in order to reduce dielectric loss tangent. Thus, the codoping increases the of SrB _1.9Y _0.1Nb _1.95V _0.05O ₉ (Y0.1V0.05) ceramic whereas, they were significantly decreased in the case of SrBi _1.8Y _0.2Nb ₂O ₉ (Y0.2) ceramic. Y0.1V0.05 sample makes up the highest efficient charge transfer, followed by Y0.2 sample representing the lowest.
