Abstract

Abstract This invention is a process for forming electrical conductors in the form of filaments which exhibit properties of electrical superconductivity at ambient or normal room temperature. The process includes the preparation of a molten mixture of conducting and insulator materials, the introduction of the nearly homogeneous mixture between electrodes across which a voltage is applied causing fine filaments to be formed having a diameter within the range of 10 to 1,000 A. The filaments thus formed give almost no resistance to the passage of the electricity therethrough at room temperature thus effectively forming an ambient temperature superconductor.
