摘要
以锶永磁铁氧体Y30H-1的预烧料为原料,采用工业化生产工艺,分别加入La2O3、Co2O3和Pr6O11三种稀土氧化物添加剂,系统地研究了三种添加剂的添加量对磁体的剩磁以及内禀矫顽力的影响,并对各自的作用机理进行了分析。
Take pre-sintering material of strontium permanent magnetic ferrite Y30H-1 as the raw material,adopt industrial manufacture process, adding three kinds of rare-earth oxide additives La2O3. Co2O3 和 Pr6011 respectively, research is made on effects of addition quantity of three additives on remanence of magnet and intrinsic coercivity systematically, and their own mechanism was also analyzed.
