A SURVEY OF INORGANIC PIEZOELECTRIC MATERIALS

Abstract

An exhaustive survey oI inorganic piezoelectric materials was made in an efiort to develop improved crystals, particularly for underwater sound gear. The field of water-soluble materials was covered thoroughly enough that further prospecting appears unprofitable. The results of this survey, together with all major surveys by previous investigators, are presented in a single table. Sufficient data are presented, concerning the piezoelectric activity of each of the materials investigaled to indicate whether they justify further investigation for various applications.
