In this study lead-free ceramics with a formula (1-x)(K0.5Na0.5)Nb1-ySbyO3-xBaTiO3
have been synthesized and studied. XRD studies showed that all compositions have
perovskite structure with monoclinic or tetragonal cell depending on substitution level.
KNN ceramics with BaTiO3 have more homogeneous structure and increased density
in comparison with pure KNN or antimony substituted KNN. Dielectric measurements
revealed diffuse phase transition.
