Abstract
Ultrafine amorphous FeNiB powder was prepared by potassium borohydride reduction by mixing the aqueous solutions in a bath of supersonic osc illator. Different mixing ratios of potassium borohydride to metal sal t were applied. Analysis of the composition of the sample and the Fe2 and Ni2+ remaining in the filtrate after preparation shows that a qua ntity of KBH4 about 1.5 times the stoichiometrical quantity is enough. Mossbauer measurements were performed at room temperature and it was found that excess KBH4 makes no distinct difference in the spectra of the samples.
