| Abstract: | We observed the evolution of polarization states and electromechanical coupling in (1 - x) AgNbO3-xNaNbO3 solid solutions using dielectric and strain hysteresis loop techniques and show that the polarization evolves from the ferrielectric ordering in AgNbO3 to the ferroelectric ordering in NaNbO3. The crossover between these two states occurs in the solid solution with x ≈ 0.8. A strain level ≈ 0.20% is available in the ceramics of these solid solutions. Such a large electromechanical effect might be interesting for the development of piezoelectric materials. |
