“…As form the ternary compound RE12Fe57.5As41 (RE=La, Ce) and FeAs at 1173 K [13][14] , whereas the Re-Fe-As ternary system forms La10Fe50As40 15 at 1223 K. In recent years, one of products of RE-Fe-As ternary system named EuFe2As2 [16][17][18][19][20] has attracted significant attention. Xie 21 and Fu 22 investigated the interaction of Nd-Fe-As system at high temperatures and found that the formation of the ternary compound NdFeAs depends on the formation of NdAs and FeAs2.…”

In this study, neodymium and arsenic were sealed into industrial pure iron cylinders at a temperature of 1223 K for 50 h. The interaction mechanism of the Nd-Fe-As system at various atomic ratios was investigated by optical microscopy, X-ray diffractometry, and scanning electron microscopy. Binary compounds Fe12As5, NdAs, Fe2As, and Fe17Na2 were the main products formed, with traces of NdFeAs compounds. In addition, at high temperatures, As content affected the diffusion of Fe atoms; the diffusion of Fe increased with an increase in the atomic ratio. Furthermore, the diffusion ability of Nd was weaker than that of As. The major diffusion mechanism of Nd was through the Fe atomic vacancy mechanism. As mainly bind to Fe to form Fe and As compounds. The formation of ternary compounds was confirmed by laboratory experiments and mismatch calculations.

In this study, neodymium and arsenic were sealed into industrial pure iron cylinders at a temperature of 1223 K for 50 h.
