用ＫＢＨ４化学还原ＦｅＳＯ４和Ｎａ２ＷＯ４制备了ＦｅＷＢ合金粉末。研究了改变溶液中的金属盐比例及ＫＢＨ４浓度对制备的影响。Ｘ射线衍射及电镜分析表明，合金粉末为３０～１００ｎｍ球形粉末，结构为非晶态。实验表明，有些粉末中有明显的非晶氧化物存在。
FeWB alloy powder was prepared by chemical reduction of FeSO4 and Na2WO4 with KBH4. The effect of varying the ratio of metal salts in solution and the concentration of KBH4 on preparation was investigated. X-ray diffraction and electron microscopy analysis showed that the alloy powder is spherical powder with 30-100nm structure and the structure is amorphous. Experiments show that some powders have obvious amorphous oxides.
