potassium sodium niobate

Potassium sodium niobate (KNN) thin films are potentially useful for energy harvesting devices and lead-free piezoelectric microelectromechanical systems. This work reports the activation energies nucleation, growth perovskite phase transformation from a 0.5% manganese-doped KNN 2-methoxyethanol-based solution modified with acetylacetone excess alkali precursors. The were annealed in rapid ther...

Effect of Mn Doping on the Microstructure and Electrical Properties of Potassium Niobate Ceramics Using Plasma Spraying

Journal: :Actuators 2022

KNN piezoelectric ceramics are of great importance in the field scientific research due to their high Curie temperature, good electrical properties, etc. The application potassium sodium niobate K0.5Na0.5NbO3 (KNN) is strictly limited volatility Na+ and K+ its leakage current. In order investigate effect Mn doping on KNN-based ceramic coatings, KNN-0.02Mn (KNMN) coatings were successfully prepa...

Studying the Effects of Nano Sintering Additives on Microstructure and Electrical Properties of Potassium-Sodium Niobate Piezoceramics

Journal: Advanced Ceramics Progress 2018

Mohammad Ali Askari Zamani, Raziye Hayati, Reza Bazargan Lari, Zohre Balak,

In this paper, lead free (K0.48,Na0.52)NbO3 (KNN(48-52)) piezoelectric ceramics were made by conventional solid state sintering process. Additives of nano ZnO (n-ZnO), nano CuO (n-CuO) and nano SnO2 (n-SnO2) were used in order to decrease the sintering temperature, as well as modifying the dielectric, piezoelectric and ferroelectric propert...
