  • Electrodes for making nanocarbon-infused metals and alloys
    Patent number: 12087828
    Abstract: A method for preparing a covetic, nanocarbon-infused, metal composite material is described is herein. The method comprises heating a stirring molten mixture of a metal (e.g., Cu, Al, Ag, Au, Fe, Ni, Pt, Sn, Pb, Zn, Si, and the like) and carbon (e.g., graphite) at a temperature sufficient to maintain the mixture in the molten state in a reactor vessel, while passing an electric current through the molten mixture via at least two spaced electrodes submerged or partially submerged in the molten metal. Each of the electrodes has an electrical conductivity that is at least about 50 percent of the electrical conductivity of the molten mixture at the temperature of the molten mixture. Preferably, the conductivity of the electrodes is equal to or greater than the conductivity of the molten mixture.
