Abstract (en)
[origin: WO2012004236A1] The invention relates to lamina-like iron pigments produced by the deformation of carbonyl iron powder, the lamina-like iron pigments having a size distribution of a D-50 value in a range of 3 to 16 µm and a size-to-thickness ratio in a range of 2 to 50. The invention further relates to a magnetorheological fluid containing the lamina-like iron pigments according to the invention, and to a device containing the magnetorheological fluid.
