摘　　要：探讨了Fe（CO）5热分解温度（Fe的氮化温度）、NHa流量及表面活性剂对制备氢化铁磁性液体的影响结果表明，将Fe（CO）5热分解温度控制在180—210℃，并通入过量的NH3及采用与纳米级氮化铁磁性颗粒和载液相匹配的表面活性剂可以制备出性能较好的氮化铁磁性液体.The influences of Fe(CO)5 thermal decomposition temperature (iron nitriding temperature), the flow of NH3 and surface activated agent on the preparation of nitride iron magnetic fluid were discussed. The result shows that the appropriate Fe(CO)5 theraml decomposition temperature is 180 to 210℃. Excessive NH3 and surface activated agent suitable to nanometer iron nitride magnetic particle and carrier liquid are necessary to preparing nitride iron magnetic with favorable property.
