TL;DR: In this paper, the properties of piezoelectric crystals and ceramics are reviewed as they affect use of such materials in electroacoustic transducers and extensive data on lead titanate-zirconate-ceramics is presented to help in selection of the appropriate material for a variety of applications in the lower and medium frequency range.
Abstract: Properties of piezoelectric crystals and ceramics are reviewed as they affect use of such materials in electroacoustic transducers. Extensive data on lead titanate-zirconate ceramics are presented to help in selection of the appropriate material for a variety of applications in the lower and medium frequency range, up to several megacycles per second. Quartz and several recently discovered piezoelectric crystals will share the higher megacycle range.

TL;DR: The lower frequency range is now covered almost exclusively by the piezoelectric ceramics which date from the late 1940's, and the upper frequency range was covered by new piezolectric crystals discovered in the 1960's as mentioned in this paper.
Abstract: Piezoelectric crystals and ceramics are used as detectors and radiators of acoustic power from very low frequencies to above 109 Hz. The lower frequency range is now covered almost exclusively by the piezoelectric ceramics which date from the late 1940’s, and the upper frequency range is covered by new piezoelectric crystals discovered in the 1960’s. The very highest frequency range has been opened up by oriented deposited films of several of the new crystals.

TL;DR: In this paper, the pyroelectric effect was demonstrated unambiguously for (NH 4 ) 2 Ln(NO 3 ) 5 ·4H 2 O (Ln = La, Ce, Pr, Nd).
Abstract: For crystals of (NH 4 ) 2 Ln(NO 3 ) 5 ·4H 2 O (Ln = La, Ce, Pr, Nd), the piezoelectric and the pyroelectric effect was demonstrated unambiguously. X-ray structure determination shows that all four compounds are isomorphic, with monoclinic, non-centrosymmetric space group Cc, and are further isomorphic to the related rubidium compounds Rb 2 Ln(NO 3 ) 5 . 4H 2 0. Large single crystals of the colourless compounds (NH 4 ) 2 La(NO 3 ) 5 ·4H 2 O and (NH 4 ) 2 Ce(NO 3 ) 5 ·4H 2 O were grown. On the basis of determined precise refractive indices and their dispersion in the wavelength region 0.365-1.083 μm, phase-matching conditions for collinear second harmonic generation were analyzed. In both crystals, type I phase matching can be realized for wavelengths from 0.893 μm (La) or 0.892 μm (Ce) to the near IR, where first absorption bands appear.
