Research output: Contribution to journalConference article

Abstract

The principle of the capacitance dilatometer is described, the DC servo stabilization of the sensing capacitor which is the key to improved stability and sensitivity discussed, and the experimental arrangement detailed. The development of a unique new AC calibration capacitor is briefly described and finally some examples are given of piezoelectric and electrostrictive crystals and ceramics which have been measured on the instrument.
