烧结钕铁硼磁体及其制备方法

, 2015
本发明提供一种烧结钕铁硼磁体及其制备方法，其成分为（RE）aFebMcCodBe，其中，RE为稀土金属元素，M为Cu、Al、Ga、Za或Nb中的一种或几种，且28≦a≦33,0＜c≦5,0＜d≦2,0＜e≦1.5,b=100-a-c-d-e；所述烧结铁钕硼磁体中的稀土元素含量呈一定的浓度梯度，且晶界的稀土元素含量大于晶粒内部的稀土元素含量。本发明的钕铁硼磁体不仅具有高矫顽力，而且还具有较好的温度稳定性。本发明的制备方法在提高钕铁硼磁体矫顽力的同时不会引入对矫顽力有恶化作用的氢原子、氧原子或氟原子 ...

碳饱和铁水与CaO-SiO_2-V_xO_y熔渣平衡体系间各组元的分配

, 1991
在1450～1580℃范围内,对钒、硅及磷、硫等元素在碳饱和铁水与CaO-SiO_2-V_xO_y渣系间的分配进行了实验研究。结果表明:随着渣碱度B(CaO/SiO_2)的增加,钒、硅及磷、硫的分配比将增大;而提高温度将降低钒、硅在渣-铁间的分配比。应用光学碱度的概念表征熔渣的碱度,考察了在不同光学碱度及不同温度下,该渣系容钒、容磷和容硫的能力,表明光学碱度增加,渣中的钒容量,磷容量及硫容量随之增大,且它们都具有较好的线性关系。升高温度,将有利于增大渣的硫容量,但容钒 ...
