Abstract

Fe-B alloys have been prepared by reduction of Fe ions by NaBH4 in aqueous solutions. The boron content was found to vary with pH. For pH between 5 and 7, amorphous Fe72B28 powders were produced. Outside this pH range also alpha-Fe appeared in the samples. However, for pH=8 amorphous Fe86B14 was formed, constituting about 90% of the sample.
