M.Mahmoudi等人采用球磨和随后烧结法,从原始Fe2O3、Sm2CO3及Li2CO3混合物制得纳米晶永磁铁氧体,Sm的含量x值设定为0,0.05,0.1及0.2。就成分对相组成、微结构及烧结体磁性影响进行研究。X-射线衍射测定结果表明,800℃烧结后形成单一铁氧体相,而Sm量增多导致形成第二相SmFeO3晶格常
M. Mahmoudi et al. Employed ball milling followed by sintering to obtain nanocrystalline permanent ferrite from a mixture of pristine Fe2O3, Sm2CO3 and Li2CO3. The content of Sm, x, was set at 0, 0.05, 0.1 and 0.2. The composition of the phase composition, microstructure and magnetic properties of sintered body were studied. X-ray diffraction measurement results show that a single ferrite phase is formed after sintering at 800 ° C, and an increase in the amount of Sm results in the formation of a second-phase SmFeO3 lattice
