The Ni-Zn synthetic ferrite were acquired from thermally decomposing the metal nitrates Fe(NO 3 ) 3 . 9H 2 O, Zn( NO 3 ) 2 . 6H 2 O, Ni( NO 3 ) 2 . 6H 2 O, and Cu( NO 3 ) 2 . 3H 2 O at 150 ? C for 24 hours and was calcined at 500 ? C . Each of those was pulverized for 3, 6, 9, and 12 hours in a steel ball mill and was sintered between 700 ? C and 1,000 ? C for 1 hour, and then their microstructures and electromagnetic properties were examined. We could make the initial specimens chemically bonded in liquid at the temperature as low as 150 ? C , by using the melting points less than 200 ? C of the metal nitrates instead of the mechanical ball milling, then narrowed a distance between the particles into a molecular level, and thus lowed sintering temperature by at least 200 ? C to 300 ? C . Their initial permeability was 50 to 400 and their saturation magnetic induction density and coercive force 2,400 G and 0.3 Oe to 0.5 Oe each, which were similar to those of Ni- Zn ferrite synthesized in the conventional process. In the graph of initial permeability vs frequencies, we could observe a 180 ? C rotation of the magnetic domain, which appears in a broad band of microwave near the resonance frequency.

Keywords:metal nitrates;microstructure;initial permeability;magnetic induction
