Description

Nanometer Iron tetroxideï&frac*4;ˆMH-Fe3O4ï&frac*4;‰ ProductCharacteristics: Nanometer Iron tetroxide si a kind of ferrite, namely Fe2+Fe3+ï&frac*4;ˆFe3+O4ï&frac*4;‰(2+and3+ representative valence of iron).In the Fe3O4, the IRON two kinds of valence state, an iron atom significantly *2 prices, two iron atoms significantly *3 Price, so the Nanometer Iron tetroxide can be seen from the composition of FeO and Fe2O3 compounds, can be expressed as FeO•Fe2O3, but can not be said to be composed of a mixture of FeO and Fe2O3, which belongs to pure materials. Nanometer Iron tetroxide placed in medium , the use of plastic melting method and add the modifier method of dispersing agent, by adsorption of particles formed on the surface electric double-layer structure of nano-particles to prevent reunite dispersed preparation of a stable water-based and organic nano-magnetic fluid.
