摘要：
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- + 6 OH- --> 2Fe2B+6H2O+H2 and (2) 4Fe2+ + 2BH4- + 7 OH- --> 2Fe3B+Fe+BO2+5H2O+5/2H2.
