摘要：

Ag is frequently used as an internal electrode in multilayer ceramic capacitors (MLCCs). Controlling the co-firing process and interface between the electrode and ceramic is of great importance to obtain highly reliable MLCCs. In this paper, the sintering behavior of the co-firing system of ZnTiO3 dielectric and Ag internal electrode material is studied. Chemical reaction, interfacial microstructure and inter-diffusion are discussed, respectively, based on XRD, SEM and EDS analysis. It is shown that the introduction of Ag can affect the dielectric properties of the ceramic matrix heavily based on dielectric property measurements. (C) 2005 Elsevier Ltd and Techna Group S.r.l.
