Preparation of Potassium Niobate–Barium Titanate Ceramics Using Well-Dispersed Nanoparticles and their Dielectric Properties

Abstract:

ANbO₃ – BaTiO₃ (A=K, Na, or K_0.5Na_0.5) system ceramics were prepared using a conventional sintering method, and their dielectric properties were investigated. It was found that the dielectric constant of KNbO₃-BaTiO₃ and (K_0.5Na_0.5) NbO₃- BaTiO₃ system ceramics did not strongly depend on temperature between 20 and 400 °C, making them useful for capacitor application.
