Abstract

The chemical composition of ultrafine amorphous Fe-B powders prepared by a chemical reduction depends on the mixed molar ratio of KBH₄ to Fe ions. We propose the following reaction processes for the formation of ultrafine Fe-B powders: (1) 4Fe²⁺+2BH_4-+6OH^-→2Fe₂B+6H₂O+H₂ and (2) 4Fe²⁺+2BH_4-+7OH^-→2Fe₃B+Fe+BO₂+5H₂O+5/2H₂.
