The initial NiCuZn synthetic ferrite were acquired from thermally decomposing the metal nitrates Fe(NO₃)₃9H₂O, Zn(NO₃)₂6H₂O, Ni(NO₃)₂6H₂O, and Cu(NO₃)₂3H₂O at 150℃ for 24 hours, and then we calcined the synthetic powder at 500 ℃, pulverized each of those for 3, 6, 9, 12, and 15 hours in a steel ball mill, sintered each at 700 ℃ to 1,000 ℃ for 1 hour, and thus studied their microstructures and electromagnetic properties. We could make the initial specimens chemically bonded in liquidity at a low-temperature 150 ℃, by using the low melting points less than 200 ℃ of the metal nitrates instead of the mechanical ball-mill pulverization, then narrow a distance between the particles into a molecular one, and thus lower the reaction point of sintering by at least 200 ℃ to 300 ℃. Their initial permeability was 50 to 400 and their maximum magnetic induction density and coercive force, 2,400 G and 0.3 Oe to 0.5 Oe respectively, which was similar to those of NiZnCu ferrite synthesized in the conventional process. In the graph of initial permeability by frequencies, a 180° rotation of the magnetic domain, which appears in a broad band of micro-wave before and after the resonance frequency, could be perceived.
