A series of Fe100-xBx nanometer metallic glass powder samples were chemically propared, which have a wider range of boron contents (23≤ x≤40).Mossbauer, ICP, XRD, TEM and DSC spectroscopic studies on the samples confirmed that the reaction temperature significantly influenced the boron content, which in turn determined the structure, crystallization temperature, the conglomeration andthe size ofthe particle as well as other properties of the samples. The importance of the reaction temperature on the chemical preparation of Fe100-xBx nanometer metallic glass were revealed.
