Abstract
A method of removing tenacious oxide film from particulates, such as submicron sized superconductor powder, to enhance the electrical characteristics of superconductor wire fabricated from the powder. The method includes removing the oxide film with an alkali metal, or a hydroxide of an alkali metal, and coating or plating the particles with a metal whose oxide is easily reduced just prior to use, such as by annealing the coated particulate in hydrogen.
