Abstract

No camber and cracks ZnTiO₃ dielectrics/NiZnCu hexagonal ferrite (abbreviated to ZT/NZC) composite samples were obtained by using restricted shrinkage sintering process. The cofiring interface and ionic interdiffusion between constituents of cofired composites were investigated. The interdiffusion of ZT/NZC composite can be regarded as the semi-infinite diffusion-couple model and based on this diffusion model, the numerical simulation for the ionic composition distribution was carried out by computer, which was in agreement with the experimental results. The diffusion coefficients and activation energies for the Zn²⁺, Ti⁴⁺, Ni²⁺, and Fe³⁺ were determined, respectively. The difference between the ionic diffusion coefficients and apparent activation energies was discussed in this article.
