本文扼要报导我们结合生产对钡铁氧体 BaO6Fe_2O_3的工艺进行研究的初步的结果,近年来钡铁氧体的应用日益广泛,其原因是它不含优质永磁合金所需的半稀有金属钴和镍等,而能具有相当好的永久磁性,并且它的矫顽力较一般合金永久磁体的还大。因此如扬声器的喇叭芯,小型电机的磁体和电子束聚焦磁体以及中级仪表中的永久磁体等都已大量地用钡铁氧体来制造,生产钡铁氧体的工艺设备和工艺过程不算烦复,也是它所以广泛应用的一个原因。钡铁氧体的磁性是所谓“类微粉型”的,即共磁化机构是由接近单畴尺寸的颗粒所决定,它
In this paper, we briefly report the preliminary results of our research on the production of barium ferrite BaO6Fe_2O_3. Barium ferrite has been widely used in recent years because it does not contain the semi-noble metal cobalt Nickel, etc., but can have a fairly good permanent magnetism, and its coercivity than the average alloy permanent magnet is still large. Therefore, such as speaker speaker core, small motor magnets and electron beam focusing magnets as well as mid-level instruments in the permanent magnets have been widely used to manufacture barium ferrite, barium ferrite production process equipment and processes are not annoying Complex, it is also a reason why it is widely used. The magnetism of barium ferrite is so-called “micron-type”, that is, the co-magnetization mechanism is determined by particles close to a single domain size, which
