Low temperature sintering of iron deficient hexagonal CO(2)Z type ferrites is attempted to prepare a chip inductor for ultra high frequency uses. It should be attained below the melting point of silver (960 degrees C) used as the electrode material of the chip inductor. The best result is obtained for the sample with the composition 2.15Co(0.6)Cu(0.4)O(.)3Ba(0.79)Sr(0.16)Bi(0.05)O(.)9.725Fe(2)O(3) sintered at 925 degrees C containing 0.5 wt.% of lithium bismuth oxide as a sintering additive. Its density and permeability reaches 5.0 g/cm(3) and 7, respectively. As a result, the impedance of the chip inductor also reaches 390 ohm at 2 GHz using this material. (c) 2005 Elsevier Ltd.
