摘　　要：高磁导率800铁氧体是制作高感量叠层片式电感器的关键材料,以NiCuZn体系为基础,通过选取缺铁量配方,调节n(Ni)∶n(Zn)及添加适量CuO、Bi203等方法,研制出了结构致密、晶粒大小在1-3 μm,烧结温区宽(865-895℃),起始磁导率μi达到800±10%,能与Ag内电极匹配共烧的高磁导率铁氧体材料.High μi800 ferrite is a key materials of manufacturing high inductance multilayer chip inductor. NiCuZn based ferrite system was taken as the research object, and the μi800 ferrite materials, which have high densification, grain size between 1 and 3μm, wide sintering temperature （865-895℃）,μi =800±10%, good firing match with Ag internal electrode slurry, are obtained by selecting Fe-deficiency formation, adjusting Ni/Zn mole ratio and adding suitable amount of CuO and Bi2O3.
