Abstract

Ceramic pellets of K_1-xNa_xNbO₃ system (for x = 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.7) have been prepared by solid-state reaction method and sintering process. The prepared samples were characterized by XRD technique. All prepared samples show orthorhombic structure at room temperature. Frequency variations of dielectric constant, loss tangent, and electrical conductivity have been investigated, at room temperature, in the frequency range 1-40 MHz. It is observed that, dielectric constant decreases as sodium is mixed by a step of 10% in potassium niobate.
