- Abstract
Acoustic emission, dilatometry, and optical microscopy were used to study the polarization of PKR-70 PbTiO[sub 3] ferroceramic samples. It was established that in an electric field higher than 2.5 kV/mm the piezo-effect in the samples acquires an infinite anisotropy, accompanied by acoustic-emission and dilatometric anomalies. It is shown that this anisotropy of the piezoeffect is caused by microcracking of the samples in the direction of the polarizing field.
