| 摘 要： | 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。

| Abstract: | The Fe W B alloy powders were prpared by chemical reduction of FeSO 4 and Na 2NO 4 wirh KBH 4. The effect of changing the ratio of metallic ions and the concentration of KBH 4 in the solution on its preparation was studlied. The rcsulls from XRD and electron microscopy analyses showed that the powders are 20-100 nm spherical particles with an amorphous structure. Some of them are covered with an oxide film. |
