• Elastic properties of PbZrO_3 and its solid solutions with PbTiO_3, BaZrO_3 and SrZrO_3 were studied by measuring resonant frequencies of bars by the composite-bar method. In the antiferroelectric range, they show elastic behaviors similar to barium titanate; and to explain these anomalies, interactions between strains and anti-parallel oriented dipoles-micro-piezoelectric effects-were introduced in a phenomenological theory. It was also pointed out that the elastic compliance coeffcient for constant polarization (s^P) of BaTiO_3 changes discontinuously at the Curie point and that the Devonshire's theory is insufficient. In addition, it was revealed from elastic and dielectric measurements that (Pb_<0.85>-Sr_<0.15>)ZrO_3 has another new phase, the nature of which, however, could not be determined.
