摘要/Abstract

摘要： 对以气相液相反应法制备氮化铁磁流体进行了探索,并摸索到制备氮化铁磁流体的工艺流程,所研制的氮化铁磁流体磁饱和强度达到0.05T(脓缩前),并将其应用在静态密封上,成功地研制出磁流体密封安全阀.

关键词: 氮化铁磁流体, 纳米微粒, 磁饱和强度

Abstract: The gas-liquid reaction method was used to prepare iron-nitride magnetic fluids, and the optimum conditions of prepartion were found out. The specific magnetization intensity of iron-nitride magnetic fluid prepared reached 0.05T(before being condensed), and the iron-nitride magnetic fluids obtained were applied in static sealing valves made by our group.

Key words: iron-nitride magnetic fluid, nanometer particle, magnetic saturation
