Y and V codoped SrBi₂Nb₂O₉ 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 SrBi₂Nb₂O₉. 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 SrBi₂Nb₂O₉ lattice in order to reduce dielectric loss tangent. Thus, the codoping increases the of SrB_1.9Y_0.1Nb_1.95V_0.05O₉ (Y0.1V0.05) ceramic whereas, they were significantly decreased in the case of SrB_1.8Y_0.2Nb₂O₉ (Y0.2) ceramic. Y0.1V0.05 sample makes up the highest efficient charge transfer, followed by Y0.2 sample representing the lowest.
