Abstract
The newly discovered phenomenon, electric-field-induced formation of superconducting balls, is effective in separating superconducting particles from a mixture with nonsuperconducting particles. In a suitable strong electric field, superconducting particles cling to the electrodes, while normal conducting particles bounce between the electrodes. The superconducting particles could then be collected from the electrodes. To separate superconducting particles from insulating ones, a moderate electric field is applied to force insulating particles to the electrodes to form short chains while keeping the superconducting particles in the middle of capacitor. This technology will be very useful in the fabrication of superconducting materials.
