This work is an initial response to the demand for miniaturization of electronic circuits and the shift to higher operating frequencies. Development of high-density and low-magnetic-energy loss in the Ni0.76-x Mg0.04+x Ca0.005 Co0.1 Cu0.075 Zn0.04 Fe1.96 O3.96 system, where x=0.01, 0.02,0.03 and 0.04, was carried out. A conventional ceramic processing technique based on solid-state chemical reactions was employed. A hard option, that of using low-grade production oxide powders (≈ 99.1%) was taken. The microstructure was tailored using CuO as a sintering aid. The formulation employed the Co2+ to broaden the operating frequency in the MHz region, Mg2+ to increase the electrical resistively and Ca2+ to neutralize the presence of SiO2, thus blocking the intergranular eddy currents hoppings. The air sintered (1140 ° C) material showed small-grain (≈ 2.3 μm) microstructure. |
