Abstract

Theoretical equations for the dielectric, elastic and piezoelectric constants of a diphasic composite changing its connectivity from 3-0 (or 0-3) to 3-3 are obtained based on a model combining cubes ( 3-0 or 0-3) and 3-3 models. This theory is applied to the experimental results for the dielectric constant of a Pb(Mg_1/3Nbr_2/3)O₃-pyrochlore phase mixture and for dielectric, elastic and piezoelectric constants of porous PZT ceramics, where good agreement between experimental and theoretical results is observed
