Manganese zinc ferrite material with high magnetic conductivity and temperature stability and preparation method thereof
The invention belongs to the technical field of manganese-zinc soft magnetic ferrite materials, and particularly discloses a manganese-zinc ferrite material with high magnetic conductivity and temperature stability and a preparation method thereof, and the fluctuation of the initial magnetic conductivity of the material in a wide temperature range of-40 DEG C to 70 DEG C is maintained in a relatively small range. The material comprises a basic component and an auxiliary component, wherein the basic component is composed of 53.5-54.5 mol% of ferric oxide, 18.5-19.5 mol% of zinc oxide and the balance of manganese oxide; the auxiliary component is prepared from the following components in percentage by weight: 0.02 to 0.10 percent of calcium carbonate, 0.002 to 0.01 percent of nano silicon dioxide, 0.01 to 0.05 percent of niobium pentoxide, 0.10 to 0.30 percent of titanium dioxide and 0.05 to 0.15 percent of cobaltosic oxide based on 100 percent of the main component. The preparation method comprises the steps of weighing, mixing, pre-sintering, ball-milling, sanding, granulating, forming and sintering, and the temperature stability performance of the initial permeability of the material is improved by controlling the proportion of basic components and auxiliary components.
