日本近几年来正在开发使用铁-硅-硼系和铁-硼-碳-硅系的非晶态合金。为了使这种材料具有能量损失少和磁性稳定的性能,对其所用的原料——硼铁的成分提出了相应地要求。尤其要求硼铁中铝、硫、碳含量尽可能低一些。现将几种生产硼铁的方法综述于后。一、高纯硼铁的精炼以往,生产硼铁的方法,一般是铝热法和电热法。前者生产的产品,其铝含量为7—12%。当然这可能是为了提高硼的回收率而加了过量铝,或者是使用单一的铝为还原剂,如果利用一部分镁粉或铝镁合金粉,则其铝含量可能要低一些。我国目前铝 Japan has been developing amorphous alloys using iron-silicon-boron systems and iron-boron-carbon-silicon systems in recent years. In order to make this material with less energy loss and magnetically stable properties, the material used for its - ferroboron made the corresponding requirements. In particular, the requirements of boron, iron, aluminum, sulfur, carbon content as low as possible. Now several kinds of ferroboron production methods reviewed later. First, the refinement of high purity ferroboron In the past, the production of ferroboron method, the general method is aluminum and electric heating method. The former products, the aluminum content of 7-12%. Of course, this may be to increase the recovery rate of boron with excess aluminum, or use a single aluminum as a reducing agent, if the use of a part of magnesium powder or aluminum-magnesium alloy powder, the aluminum content may be lower.
