All ceramics were fabricated by pressureless sintering technique. Li, Li-Ta modifications were improved densification and thus dielectric properties. The dielectric properties of Li and Ta modified KNN ceramics were analyzed using AC impedance spectroscopy as a function of frequency from 100 Hz to 10 MHz in temperature range from 673 K to 798 K.eninfo:eu-repo/semantics/closedAccesslead-freedielectric propertiesLi and Li-Ta modified KNNimpedance spectroscopyConference ObjectWOS:000326960202159N/A
