Transformer based on ferrite material
The invention relates to a transformer, in particular to a ferrite material with high magnetic conductivity, high Curie temperature, high impedance characteristic and low loss and a preparation methodthereof. The ferrite material comprises main components and auxiliary components. The main components comprise ZnO, Fe2O3 and MnO, the auxiliary components comprise one or more of CaCO3, SiO2TiO2, V2O5, Co2O3, Nb2O5, Bi2O3, MoO3, ZrO2 and NiO, and the process steps adopted by the preparation method of the ferrite material comprise the following six steps: (1) grinding treatment; (2) presinteringtreatment; (3) sanding treatment; (4) spray granulation; (5) molding treatment; (6) sintering treatment. Compared with the prior art, the ferrite material disclosed by the invention has the excellentcharacteristics of high magnetic conductivity, high Curie temperature, high impedance characteristic, low magnetic loss and the like, and a transformer prepared from the ferrite material also has excellent performance.
