Ceramic pellets of Potassium Sodium Niobate (K x Na 1 - x NbO 3 ) system have been prepared using solid solution reaction method. The prepared samples were characterized using X-ray diffraction method and grain size have been calculated using SEM photographs. Dielectric constant, loss tangent, and electrical conductivity of prepared samples have been measured at different frequencies and temperatures. The concentration, frequency, and temperature dependence of dielectric properties have been studied.
