The Study For Basic Physical Characters And Field-induced Transmitted Light Of CoFe₂O₄ Self-formed Ferrofluid

The preparation technique of self-formed ferrofluid has been introduced in this paper, at the same time the particles size distribution, the basic physical characters include density, stability, viscosity in zero field and property of magnetization, the field-induced transmitted light of self-formd ferrofluid has been studied. The amelioration of the preparation technique and the studying of the particles size distribution make the prepare for the quantificational studying of basic physical characters, however, the quantificational studying of basic physical characters make the prepare for the quantificational studying of field-induced transmitted light in ferrofluid. The development of quantificational studying from preparation to field-induced transmitted light can be seen in this paper:(l)The value of Q has been confirmed. The same chemical composition offerrofluids can be obtained, and be independent of one time preparation withthis Q value. The amelioration of the preparation technique make theferrofluids which prepared any times has the same volume fraction.(2) Known the acetone has the less effect to the forming of ferrofluids' particles,...
