Abstract

A transducer includes as an operating element a sintered ceramic material as disclosed in Specification 698,946 viz. a solid solution of one or more of the metatitanates, metazirconates and metastannates of barium, calcium and strontium with a minor amount of one or more of those of zinc or cadmium.
