| 摘 要： | The paper first reported the preparation of ultrafine Fe3O4 powder about 8～10nm by improved chemical pre-cipitation 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 ad-dition， 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.
