Abstract

PZT ceramics are presented which, like PbNb₂0₆, have very low mechanical Q values and therefore are suitable for wideband ultrasonic transducers. Compared with PbNb₂0₆ they afford the advantage that they are five times more efficient. The high internal friction in these ceramics occurs in the region of the grain boundaries and is probably of a viscoelastic nature.
