摘要
本文选用NH3·H2O作沉淀剂,用共沉淀的方法制备出了超微磁性粒子(5~100nm),优化出了最佳的制备流程,着重研究了熟化对Fe3O4粒子的磁性能的影响,并对此影响提供了理论的分析和研究.
NH 3·H 2O is chosen to act as preciptating agent. Ultrafine magnetic Fe 3O 4particles (50~100nm) are prepared by copreciptation. The best preparation circuit is optimized. The theoretical research about the effect of aging on Fe 3O 4magnetism has been also offered in this paper.
