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++2BH4−+6OH→2Fe2B+6H2O+H2 and (2) 4Fe2++2BH4−+7OH→2Fe3B+Fe+BO2+5H2O+5/2H2.
