Abstract
Solid solutions and composites of a mixture of (K_0.5Na_0.5)NbO₃ (KNN) and SrTiO₃ (ST) were respectively synthesized by different process routes using a conventional solid state reaction. All starting materials were mixed simultaneously and calcined at 800 ^oC for 4 h to obtain the solid solutions of KNN-ST. Meanwhile, the composites..... More
