Abstract :
Many ceramics have been studied due to their importance in the fabrication of multilayer ceramic capacitors and actuators. Potassium Sodium Niobate (K0.5Na0.5NbO3) is one of the most promising candidate of lead free piezoelectric ceramics used in sensors and actuators. K0.5Na0.5NbO3 (KNN) was successfully synthesized by solid state reaction method. X-ray diffraction studies (XRD) confirmed the single phase structure. Capacitance of the sample sintered at 11000C as a function of temperature and frequency was measured. The variation of electrically induced strain with the applied electric field has also been studied.
