| Piezoelectric ceramics-a class of oxidic ferro-electric
materials with specific modifications-display excellent
electro-mechanical properties for use as transducer elements
in the production of high voltages, ultrasonics,
wave fiilters, radiation detectors and for pressure measurements.
The paper gives an account of the efforts made
in the direction of indigenous development and production
of lead zirconate titanate type of materials at Armament
Research and Development Establishment and describes
their characteristics and typical uses. |
