This paper presents the co-firing behavior and interfacial structure of Ni–Zn–Cu ferrite/Al2O3–SiO2–B2O3 glass-ceramic composites. An effective multilayered structure is proposed to prevent the camber and crack problem due to the shrinkage behavior and thermal expansion coefficient difference during the sintering process. Bi2O3 not only plays a role as a sintering aid to reduce the sintering temperature of Ni–Zn–Cu ferrite but it also diffuses into Al2O3–SiO2–B2O3 glass-ceramic forming a stronger bonding at the interface after sintering.
