Processing and characterizations of BNT-KNN ceramics for actuator applications
Processing and Application of Ceramics, 2016 BNT-KNN powder (with composition 0.93Bi0.5Na0.5TiO3–0.07K0.5Na0.5NbO3) was synthesized as a single perovskite phase by conventional solid state reaction route and dense ceramics were obtained by sintering of powder compacts at 1100 °C for 4 h. Dielectric study confirmed relaxor behaviour, whereas the microstructure study showed sharp cornered cubic ...

Dielectric relaxation of NKN-BNT porous green body
Procedia Engineering, 2012 Abstract0.98Na0.5K0.5NbO3 –0.02Bi0.5Na0.5TiO3 (NKNBNT) nano-powder was fabricated by mechanical alloying method. The NKNBNT particle and water molecular on the particle surface became an insulator/ conductor system because of the surface defect and moisture absorption of Na and K ions.
