In this paper, the authors analyzed the effect of the 90° domain structure, the form of crystalline inclusions, the remanent polarization of the ceramics, molar Ca concentration, and other factors of the effective piezoelectric coefficients of the composite.Abstract:
In the framework of the model of a piezoelectrically active ferroelectric crystal-ceramic composite of the 0–3 type, the concentration dependences of the effective piezoelectric properties of this composite are determined. Two examples of such composites are discussed: the single-domain PbTiO3 crystal (Pb1 − x
Ca itx)TiO3 ceramic and the polydomain PbTiO3 crystal (Pb1 − x
Cax)TiO3 ceramic. Based on these examples, we analyzed the effect of the 90° domain structure, the form of crystalline inclusions, the remanent polarization of the ceramics, molar Ca concentration (x), and other factors of the effective piezoelectric coefficients e
