Description

Some years after the publication of Vol. III/11 and its supplement III/18 dealing with elastic, piezoelectric, pyroelectric and optical properties of crystals, a complete recompilation of the data of these volumes and of new data was performed. Because of the growth of this subject matter it was found convenient to divide the material into four volumes, III/29a and b forthe low frequency properties and III/30a and b for high frequency propertiesof dielectric crystals. The first subvolume III/29a, already published in 1992, contains exclusively second and higher order elastic constants including temperature and pressure coefficients. The present second subvolume III/29b essentially contains relative dielectric constants and piezoelectric constants and their temperature coefficients, as well as electrostrictive and pyroelectric coefficients and electromechanical coupling factors of dielectric crystals. The data are given in numerous tables and figures, the latter mostly showing temperature and compositional dependences. An alphabetical index for all substances of both subvolumes listed according to their element systems and furthermore an index of chemical, mineralogical, and technical names help the reader to find data.
