Preparation method for soft magnetic ferrite with high saturation magnetic induction strength, wide temperature range and low loss
The invention discloses a preparation method of soft magnetic ferrite with high saturation magnetic induction strength, wide temperature range and low loss. The method comprises the following steps: adding yttrium oxide, cobalt oxide, copper oxide and strontium oxide into hydrochloric acid, after completion of dissolving, adding ferrous chloride, manganese chloride, zinc chloride and nickel chloride, and carrying out uniform mixing under stirring so as to obtain a material A; dripdrop adding a sodium hydroxide solution into the material A until a pH value is 9 to 11, carrying out standing and aging for 10 to 15 h, then adding triethanolamine and P123 under stirring, then carrying out standing and hydrothermal reaction, and carrying out natural cooling, washing, filtering and drying so as to obtain a material B; and adding zirconium oxide, titanium oxide, vanadium oxide, magnesium oxide, bismuth oxide, aluminum oxide, boron oxide, barium oxide, palladium oxide, tin oxide, indium oxide, calcium carbonate, tungsten carbide and an adhesive, and carrying out uniform mixing, pressing molding, sintering and cooling so as to obtain the soft magnetic ferrite with high saturation magnetic induction strength, wide temperature range and low loss.
