Abstract

Ultrasonic velocity of the piezoelectric ceramic pellets of ferroelectric material Na1-xKxTaO3 (X=0, 0.2, 0.3, 0.4, 0.5, 0.6 and 1.0) have been investigated at temperature 32 ºC and frequency 5 MHz with the help of ultrasonic c-scan system developed at NPL, New Delhi. The samples have been prepared by the conventional solid-state reaction method and sintering process.
