We hane investigated a new ferrite-ceramc composite material with inductive and capacitive properties fahcicated by a solid-state reaction method. We analyse the effects of the composite mechamism and microstrocture on the magnetic and electric properties. The resuits show that the new materials can be used not only as in ductor materials. but also as capacitor materials in the wide frequency range of 1kHz-1.8GHz. The real part of permeability of the composite material is between 10 and 5.6, the imagimary part of permeability is between 1.2 amd 0.5, and the dielectric constan isabout ten times larger than that of ordinary ferricte materials. It is suggested that the new composite materials will be widely used in anti-electromagnetic interference fields and radio frequency communication fields.
