Abstract
(1- x- z)NaNbO · xKNbO · zCuNbO ( x = 0.05-0.50, z = 0.025−0.050) ceramics have been prepared by solid-state reactions followed by sintering using standard ceramic processing. Phase relations in a portion of the NaNbO-KNbO-CuNbO system have been studied for the first time, and property-structure-composition relationships have been established for solid solutions in this system. The effect of KNbO content on the main electrical and physical parameters of the solid solutions has been shown to correlate with the position of the morphotropic phase boundaries in this system and the observed structural anomalies. The solid solutions have been demonstrated to be potentially attractive for use in ultrasonic devices. [ABSTRACT FROM AUTHOR]
