流动化学反应法制备Fe－Ni－B非晶超细颗粒的研究

Study on the Preparation of Fe-Ni-B Amorphous Ultrafine Particles by Flow Chemical Reaction

利用流动化学反应法制备了粒径大小约为１００ｎｍ的Ｆｅ－Ｎｉ－Ｂ非晶超细颗粒。以化学分析及Ｍｏｓｓｂａｕｅｒ测试作为主要方法，研究了反应液的浓度、溶液的ｐＨ值、反应液流量及搅拌速度等因素对非晶超细颗粒物性的影响。

Fe-Ni-B amorphous ultrafine particles with diameter about 100nm were prepared by means of flow chemical reaction. The effect of the concentration, the flow of the reactant solution, the pH of the reaction solution and the stirring velocity on the properties of amorphous ultrafine particles were studied by chemical analysis and Mossbauer spectroscopy.
