A carbon black composition of nickel, iron, cobalt or yttrium coated carbon blacks, mixtures of such metal-doped carbon blacks with thermoplastic material or rubber as well as applications of the metal-coated carbon blacks are disclosed. The material has ferromagnetic properties and enables applications in materials that are influenced by magnetic and / or electrical and / or electromagnetic fields. The other application is the use in carbon black reactors as a catalyst or core for a new generation of nanostructures of carbon black, in particular carbon nanotubes. |
