Preparation method and application of ferrite-ceramic heterogeneous co-fired material
The invention discloses a preparation method and application of a ferrite-ceramic heterogeneous co-fired material. The preparation method comprises the following steps: preparing ferrite and ceramic with equivalent sintering temperature and shrinkage rate; ferrite and ceramic are subjected to lamination, lamination and cutting treatment to obtain a ferrite-ceramic heterogeneous co-fired material green body, and then the green body is sintered at the temperature lower than 950 DEG C to obtain a finished product; wherein the ferrite is a Li-series ferrite-sintering aid composite system or a Ni-series ferrite-sintering aid composite system, and the ceramic is a glass-ceramic filler composite system. According to the preparation method, the ferrite and the ceramic can be matched and co-fired at the temperature lower than 950 DEG C, the problem of shrinkage mismatch is avoided, and the prepared co-fired material can be applied to integrated design and manufacturing of X-millimeter wave band circulators and is beneficial to miniaturization development of T/R assemblies.
