Abstract
We investigate the ferroelectric phase evolution in AgNbO3-KNbO3 solid solutions.In the Ag-rich region, strong ferroelectricity with Pr=25 uC/cm2 was observed in the solid solutions, in which two ferroelectric phases were detected.In the K-rich region, the solid solutions show similar ferroelectric transitions to those of pure KNbO3. A strain level of 0.05% and a d33 value of 46-64 pC/N were also observed for the ceramics samples.
