Co-Firing Behavior and Interfacial Structure of BaO–TiO2–B2O3–SiO2Glass–Ceramics/NiCuZn Ferrite Composites

This paper presents the co-firing behavior and interfacial structure of BaO–TiO2–B2O3–SiO2 glass–ceramics/NiCuZn ferrite multi-layer composites. Several effective methods, such as sandwich stacking structure and sintering shrinkage modification, are proposed to prevent the camber problem due to the mismatched shrinkage during sintering process to fabricate high-frequency chip inductors that are composite by NiCuZn ferrite and dielectric glass ceramic.
