Fe2O4磁液的悬浮率测定及稳定性研究
无机化学学报，2003，19（4）：411～414，-0001，（）：
The paper first reported the preparation of ultrafine Fe3O4 powder about 8～10nm by improved chemical precipitation method, then turned it into magnetic fluid. The phase analysis, morphology, ultrafine powder size and magnetic property were measured by XRD, TEM and vibrating sample magnetometer(VSM), respectively. In addition, a new method, by analyzed the suspending percentage of Fe3O4 powder, was introduced to study the effects of concentration, pH value, centrifugal rate and time on the stability of the magnetic fluid.
