Abstract: An easy approach is suggested to obtain excellent piezoelectric performances in potassium sodium niobate (KNN)-based ceramics simultaneously with low dielectric loss (tanδ), high Curie temperature (TC), and electromechanical coupling factor (kp). Herein, a KNN-based ceramics… read more here.

Abstract: In this study, (1-x)K0.5Na0.5NbO3−xBa0.5Sr0.5(Zn1/3Nb2/3)O3, [(1-x)KNN-xBSZN] lead-free relaxor ceramics were fabricated by a conventional solid-state reaction method. X-ray diffraction and Raman spectra confirm the R-C phase transition of the ceramics. The incorporation of BSZN effectively suppressed… read more here.
