利用ＣａＨ_２作还原剂由还原扩散法制取Ｓｍ－Ｆｅ金属间化合物为了弄清利用还原－扩散法制取Ｓｍ－Ｆｅ金属间化合物的产出率和生成机制，进行了如下三种实验过程：（１）用Ｓｍ２Ｏ３＋ＣａＨ２粉末混合物球团的还原；（２）用Ｓｍ２Ｏ３、ＣａＨ２和Ｆｅ（粉末或丝）?..
Sm-Fe Intermetallics Prepared by Reduction-diffusion Method Using CaH2 as Reducing Agent In order to find out the yield and formation mechanism of Sm-Fe intermetallic compounds by reduction-diffusion method, the following three experimental processes were carried out: (1) Reduction with the Sm2O3 + CaH2 powder mixture pellets; (2) With Sm2O3, CaH2 and Fe (powder or wire)?
