Abstract

This paper presents the co-firing behavior and interfacial structure of Ni-Zn-Cu ferrite / Al₂O₃-SiO₂-B₂O₃ glass-ceramic composites. The effective multilayer structure are proposed to prevent the camber and crack problem due to different shrinkage behavior and thermal expansion coefficient difference during sintering process. Bi₂O₃ is not only a sintering aid to reduce sintering temperature of Ni-Zn-Cu ferrite but also diffuse into Al₂O₃-SiO₂-B₂O₃ glass-ceramic to form a stronger bonding at interface after sintering.
