                         cobalt ferrite (FCO), nickel-cobalt ferrite (FNICO) and BaTiO3 
                         (TB) ceramics under different sintering conditions were 
                         investigated. Subsequently, lay-ered ferrite-BaTiO3 samples were 
                         formed by uniaxial pressing of the corresponding ceramic powders. 
                         These green samples were sintered with two different sintering 
                         schedules, aiming to study the ferrite-BaTiO3 inter-faces after 
                         sintering. The analyses were made at the cross section of the 
                         interfaces and at the interface surfaces after separation of the 
                         layers. The sintered layered samples were utilized to analyze 
                         sintering mismatch, dif-fusion at the interfaces and 
                         identification of some newly formed phases. EDS analysis across 
                         the TB-FCO interface showed evidences of diffusion. It was 
                         observed that the FNICO layers were detached from TB during 
                         sintering, but the same was not observed in the TB-FCO samples, 
                         although shrinkage mismatch resulted in some defects. XRD analyses 
                         suggested the presence of Ti2O at the TB-FCO interface and 
                         BaTiNiFe10O19 at the TB-FNICO interface as products of the 
                         reactions between the ferrites and BaTiO3.",
