In a reduction-diffusion (R-D) process using Ca, the uneven distribution of Ca in the reaction vessel was found to have a significant effect on the size uniformity of the Sm2Fe17 particles. It was considered that lumps of Sm-Ca-Fe formed due to the uneven distribution of Ca, and coarse Sm2Fe17 parti...
