We have investigated the effect of electrical conductivity of the constituents on the poling behaviour of the ceramic inclusions in 0–3 ferroelectric composites which comprise a dilute suspension of spherical particles uniformly distributed in the matrix material. A new model for the pyroelectric and piezoelectric properties in terms of the poling conditions (poling field and poling time) has been developed to include electrical conductivity. Simulated results show that conductivity plays an important role in the poling process. Properly increasing the conductivity of the matrix σm can enhance the polarization in the ceramic inclusion of the composite Pi, thereby making the poling of the composite more efficient. In contrast, higher conductivity of the ceramic inclusion σi results in lower polarization Pi, which is unfavourable to the poling of the composite. These results provide insights into the observed behaviour of 0–3 composites. The model predicts the pyroelectric and piezoelectric properties under different poling conditions, which agree well with the corresponding experimental data.
