| 摘 要： | 硅油基磁流体由于具有良好的耐热性能已引起人们的关注，但与硅油相溶的表面活性剂较少，如何将磁微粒高度地分散在硅油中，是制备硅油基磁流体的关键。本文探讨了以化学共沉淀法制备的纳米Fe3O4微粒在硅油中高度分散体系形成的条件及其影响因素。提出了使磁微粒稳定地分散在硅油中的方法。

| Abstract: | Because of its good heat-resisting capability,silicon-oil-based magnetic fluid is drawing more and more people's attention.Yet the problem is that there is a little surface-active agent which can be dissolved in silicon oil.So the key to make silicon-oil-based magnetic fluid is how to fully disperse magnetic particulates into silicon oil.A new way called Common Chemistry Precipitating method in which nanometer Fe 3O 4 particulates can be fully dispersed in silicon oil,and accordingly,magnetic particulates can be dispersed in it steadily is discribed. |
