Abstract: Dielectric and electrical properties of K1−xNaxNbO3 (x=0, 0.2, 0.4) ceramics have been investigated in the temperature range 35-250°C at different frequencies in the range 0.1-1 MHz. The samples have been prepared by the conventional solid-state reaction method and sintering process. It is observed that dielectric constant, loss tangent and electrical conductivity increase with increasing temperature. Near the transition temperature, dielectric constant, loss tangent and electrical conductivity of these samples show anomalous behaviour. All the prepared samples show orthorhombic structure at room temperature.
