一种Fe-B-P超细粒子的制备方法
摘要：
一种Fe-B-P超细粒子的制备方法，在室温下，以水为溶剂，依次溶入FeCl2·4H2O、NH4Cl、柠檬酸钠、次亚磷酸钠；向溶液中加入包裹剂；滴加NaOH溶液调节溶液pH值；滴加硼氢化钠水溶液，得到黑色的Fe-B-P超细粒子悬浮液；离心分离，得到Fe-P-B超细粒子；将超细粒子收集，水洗、乙醇洗后，存放入乙醇中。本发明得到的亚微米、纳米超细粉体材料，具有高饱和磁化强度、低矫顽力是良好的软磁材料，在磁流体、电磁波吸波材料、DC-DC转换器、靶向药物等等众多领域具有着广阔的应用前景。
摘要（英）：

The invention relates to a method for preparing Fe-B-P ultrafine particles, comprising the following steps: dissolving FeCl2.4H2O, NH4Cl, sodium citrate and sodium hypophosphite to water functioning as solvent in room temperature; adding package agent to the solution; dropwise adding NaOH solution to adjusting the pH value of the solution; dropwise adding sodium borohydride solution to obtain theblack Fe-B-P ultrafine particle suspension; centrifugally separating the black Fe-B-P ultrafine particle suspension to obtain the Fe-P-B ultrafine particles; and collecting the Fe-P-B ultrafine particles, washing with water, washing with ethanol and placing into ethanol. The sub-micron/nanometer ultrafine powder material has high saturation magnetization and low coercive force, is good soft magnetic material and has wide application prospect in numerous fields of the magnetic fluid, the electromagnetic wave absorbing material, the DC-DC converter, the targeting drugs and the like.
