Abstract (en)
[origin: DE19758350C1] The invention relates to a novel magnetic liquid and to a method and device for the production thereof. The aim of the invention is to produce a magnetic liquid which is based on a polar carrier liquid having a high saturation magnetization, i.e. having a high concentration of nanometer particles and a low viscosity, and to provide a method and device for the production thereof. To this end, a magnetic liquid is provided which comprises a saturation magnetization of at least 30 mT and a viscosity under 100 mPas at 40 DEG C, whereby the carrier liquid contains essentially no dissolved components of the outer adsorption layer. In addition, a method and device are provided for the production thereof.
