Composites with a ferrite phase and a ferroelectric phase are of interest to researchers and the industry due to their potential device applications. These ferrite-ferroelectric ceramic composites show novel coupling properties including the magnetoelectric (ME) effect. ME effect is due to the cross coupling between ferroic subsystems mediated by strain interactions and are absent in either of the constituent phase individually. Since the coupling between phases is a mechanical interaction, the integrity of the constituent phases, combined with good microstructural characteristics is essential for improving the magnetic, electrical and magnetoelectric properties. In order to determine a sintering protocol where it is possible to maintain the constituents phases integrity, different sintering method/condition was performed in composite materials with different ferroelectric (PZT, PMNPT, PBN, KNN, BTO) and ferrites (nickel and cobalt) phases. The results indicated that the optimized processing condition, which the samples shows high density and high electric resistivity (in consequence of the maintenance of phase integrity), was obtained in temperature range of initial stage of sintering of the composite (determined by shrinkage measurements). The pair ferrite-ferroelectric is whom determines the temperature range that occur the initial stage of sintering the composite, and for combination that have similar ranges of temperatures for initial stage of sintering, it was observed a greater integrity of phases.
