Abstract
Low-temperature sintering Y-type hexagonal femtes were made by the ceramics method. The temperature obtaining a single phase shifted lower with the CuO content. In Ba2Co1.0Cu1.0Fe12O22, a single phase was obtained at 950°C calcination. At the same time, the shrinkage curve shifts to the low temperature, and the firing temperature that is able to get over 95% of the theoretical density has lowered from 1200°C to 1000°C by the CuO substitution. Further more, Bi2O3 addition shifted the shrinkage curve to the low temperature. Exact sintered body with 900°C sintering was obtained by 5 wt% addition. The permeability and resonance frequency were 2.3 and 5.7 GHz respectively. The permeability was improved by divalent metal substitution, Ba2Me1.0Cu1.0Fe12O22 (Me: Ni, Mg, Zn), and the highest permeability was achieved by Zn substitution. The permeability and resonance frequency were 9.7 and 1.0 GHz respectively. It is found that Ba2ZnxCu2-xFe12O22 with Bi2O3 addition show high performance as magnetic material for chip inductors.
