WebDec 1, 2024 · A novel method for preparing Sm 2 Fe 17 alloy was proposed by iron-induced SmF 3 through calciothermic reduction. • Sm 2 Fe 17 alloy with low content of … Calciothermic reactions are metallothermic reduction reactions (more generally, thermic chemical reactions) which use calcium metal as the reducing agent at high temperature. Calcium is one of the most potent reducing agents available, usually drawn as the strongest oxidic reductant in Ellingham diagrams, though the lanthanides best it in this respect in oxide processes. On the other hand, this trend does not continue to other compounds that are non-oxides, and fo…
