Influence of the borohydride concentration on the composition of the amorphous ...
Resende, Valdirene Gonzaga de; Grave, Eddy De; Costa, Geraldo Magela da; Janssens, J.A systematic study of the effect of the NaBH4 concentration upon the composites produced by chemical reduction of nano-sized goethite (_-FeOOH) particles suspended in water is presented. Amorphous Fe–B alloys with boron contents between 2 and 8 at.% have been produced. The obtained samples were characterized by X-ray diffraction, wet chemical analyses, thermal analyses, scanning electron microscopy, transmissio...
