Soft magnetic nickel-zinc ferrite material, preparation method and application thereof
The invention discloses a soft magnetic nickel-zinc ferrite material, a preparation method and application thereof. The soft magnetic nickel-zinc ferrite material comprises main components and auxiliary components, wherein the main components comprise 48.0 to 50.0 mol% of Fe2O3, 30.0 to 35.0 mol% of ZnO and 16.0 to 20.0 mol% of NiO, and the auxiliary components comprise 0.05 to 0.15 wt% of Ca2CO3, 0.01 to 0.50 wt% of CuO and 0.01 to 0.06 wt% of V2O5. According to the invention, by controlling a ternary formula system containing a cooper oxide-free main component, and controlling the mass percent of CuO in an auxiliary component to be 0.01-0.50 wt%, the ion point location of Cu is reduced, and the growth size of crystal grains is controlled, so that the microstructure in the magnetic core is optimized, the super-exchange effect of ferrite is reduced, the effects of high Curie temperature and high magnetic conductivity are achieved, the high magnetic conductivity of 1300-1550 can still be maintained at the high Curie temperature of 140-155 DEG C, and the material can be widely applied to preparation of communication base stations and servers.
本发明公开了一种软磁镍锌铁氧体材料及其制备方法和应用。软磁镍锌铁氧体材料包括主成分和副成分，其中主成分为Fe2O3 48.0～50.0mol％，ZnO 30.0～35.0mol％，NiO 16.0～20.0mol％，副成分为Ca2CO3 0.05～0.15wt％，CuO0.01～0.50wt％，V2O5 0.01～0.06wt％。本发明通过控制主成分为无氧化铜的三元配方体系，同时将副成分中CuO的质量百分比控制在0.01～0.50wt％内，减少Cu的离子点位，控制晶粒的生长大小，有利于优化磁芯内部的微观结构和降低铁氧体超交换作用，从而达到高居里温度高磁导率的效果，在140～155℃的高居里温度下仍可以保持1300～1550的高磁导率，可以广泛应用于制备通讯基站和服务器中。
