Good high-temperature stability and improved piezoelectric properties of (K0.5Na0.5)NbO3–Bi(Mg0.5Zr0.5)O3 ceramics

Good high-temperature stability and improved piezoelectric properties of... (1−x)(K0.5Na0.5)NbO3–xBi(Mg0.5Zr0.5)O3 (abbreviated as KNN–BMZ) [x = 0, 0.005, 0.0075, 0.01, 0.015, 0.02] solid solution ceramics were fabricated by an ordinary ceramic sintering technique. The piezoelectric and dielectric properties of ceramics were enhanced significantly through adding Bi(Mg0.5Zr0.5)O3. X-ray powder diffraction analysis certified that the Bi(Mg0.5Zr0.5)O3 has diffused into (K0.5Na0.5)NbO3 to form a new perovskite structure solid solution. The addition of Bi(Mg0.5Zr0.5)O3 depressed the orthorhombic–tetragonal phase transition temperature from 205 to 136 °C and tetragonal–pseudocubic phase transition temperature (Curie point) from 419 to 397 °C. Furthermore, the ceramics exhibited higher relative permittivity and lower dielectric loss than the pure (K0.5Na0.5)NbO3. Especially, when x = 0.0075, the ceramics showed the improved high relative permittivity (ε ~2024), low dielectric loss (tanδ <3.8%) and thermal stability (Δε/ε143°C ≤ ±10%) over a wide temperature range (143–337 °C). Moreover, when x = 0.005, the piezoelectric constant was improved to d 33 = 118 pC/N. These results indicated that the BMZ added ceramics have potential applications in piezoelectric and thermal stability devices. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Materials Science: Materials in Electronics Springer Journals
