[0007] Chinese patent application (CN1749209A) discloses a high saturation magnetic flux density, low-loss manganese-zinc ferrite material and its preparation method. Through doping and process control, it obtains 100kHz 200mT 45 ℃ less than 245kw / m 3 The power consumption and the saturation magnetic flux density of 1194A / m 50mT at 25°C are higher than 535mT, but the introduction of high temperature characteristics is avoided, obviously its application range is quite limited
[0008] Another example is the Chinese patent application (CN1810710A) which discloses a manganese-zinc ferrite with a wide temperature range and high magnetic permeability and its preparation method. Time stability - the specific reduction coefficient has not been studied, thus limiting its scope of use

Abstract

The invention discloses a broad temperature low standby power consumption FPT type soft magnetic ferrite and a preparation method thereof. The composition calculated by content of oxides is as follows: 52-55mol% of Fe2O3, 7-10mol% of ZnO and the balance of MnO; a first auxiliary component comprises 0.01wt%-0.1wt% of CaO and 0.005wt%-0.02wt% of SiO2; a second auxiliary component comprises one or more of V2O5, Nb2O5, Ta2O5, ZrO2 and K2O, the content is 0-0.2wt% by calculation, and a third auxiliary component comprises 0.05-1wt% of TiO2 and 0.05-1wt% of Co2O3. Pre-burning under the protection of nitrogen, sintering, the control of cooling atmosphere and the densification process are carried out, thereby leading the power consumption PCV of a magnetic core at 100kHz and 200mT within the temperature of 25 DEG C-120 DEG C to be respectively less than 400kw / m<3> and 350kw / m<3>, and a time stability indicator thereof which is a disaccommodation factor Df is less than 2*10<-6>.

Description

technical field [0001] The invention relates to a low standby power consumption FPT type wide temperature soft ferrite material and a preparation method thereof, belonging to the technical field of ferrite magnetic materials.
