| 摘 要： | 介绍了一项由自蔓延高温合成(SHS)碳包覆磁纳米粒子的系统研究。采用还原剂NaN3和三种不同氧化剂-聚四氟乙烯、六氯乙烷和六氯苯,实施了SHS制备。研究了金属前躯体(Fe(CO)5或K3Fe(CN)6])对产物的得率、反应热、形貌、结构和磁性能的影响。结果表明:有机铁前躯体和C2Cl6氧化剂反应体系可获得磁性最佳、得率最高的产物。

| Abstract: | A systematic study on the synthesis of carbon-encapsulated magnetic nanoparticles by self-sustaining high-temperature synthesis (SHS) is presented. The SHS was carried out using NaN3 as a reducer; and poly(tetrafluoroethene) (C2F4)n,hexachloroethane (C2Cl6) and hexachlorobenzene (C6Cl6) as three various oxidizers. The effect of metal precursor,(Fe(CO)5 or K3Fe(CN)6]) on the yield,reaction heat,morphology,structure and magnetic properties of the products was investigated. The highest product yield with best... |
