A study of Fe-B and Fe-Co-B alloy particles produced by reduction with borohydride

Fe-B and Fe-CO-B alloy particles have been prepared by reduction of metal ions in aqueous solution by use of KBH4 and NaBH4. It is shown that the boron content in the particles can be varied by changing the concentration of borohydride and the Fe/Co ratio. For the lowest boron concentrations a mixture of crystalline and amorphous alloysis formed. For higher boron concentrations all the material is amorphous.
