Abstract

The present paper presents experimental and theoretical studies of the effective piezoelectric properties of porous Pb(Zr,Ti)O-3 based ceramics and composites. The experimental dependence of piezoelectric coefficients and dielectric permittivity on relative density is determined for porous materials containing different piezopassive components. The piezoelectric response of these materials in a wide range of volume concentrations of the piezopassive components are analysed in the framework of a model of a modified laminated composite with 2-2 and 1-3 connectivity elements. The role of these elements in forming different concentration dependences of the effective parameters of the porous piezoceramic and piezocomposite materials is discussed.
