| Abstract: | It is illustrated in this paper that the processes of ferrofluid preparation by chemical co-precipitation method include 3 stages,i.e. solution preparation,chemical reaction and dispersion by coating.The key techniques are purity control,size control and dispersion control.The influence of process parameters in each stage upon purity and size of magnetic particles is analyzed in detail.It is turned out that the way for preparing ferrofluid with good qualty is suitable matching the process parameters between the different stages. |
