Wide-temperature high-permeability soft magnetic ferrite material and element preparation method thereof
The invention discloses a wide-temperature high-permeability soft magnetic ferrite material and an element preparation method thereof. The wide-temperature high-permeability soft magnetic ferrite material comprises a main material and an auxiliary material. The main material accounts for more than or equal to 99.50% by mass, and the auxiliary materials accounts for less than or equal to 0.5%. The main material comprises the following components in percentage by mass: 50.5%-52.5% of ferric oxide, 24.5%-26.5% of manganese oxide; and 22%-24% of zinc oxide. The auxiliary material comprises calcium carbonate, copper oxide, bismuth trioxide, silicon dioxide, tin oxide, niobium pentoxide, titanium dioxide, cobalt sesquioxide, molybdenum trioxide and tungsten dioxide. The auxiliary material is added, the total amount of the auxiliary material is controlled to be 0.5% or below, and the magnetic flux density of the ferrite material is enhanced through matching of the auxiliary material, so that the environmental adaptability is improved, the problem that the loss is too large when the ferrite material is used in a severe environment is solved, and the comprehensive performance of the wide-temperature-range high-permeability soft magnetic ferrite material is improved.
