Abstract
A process for depositing a silver coating onto a superconductor involves placing the superconductor into an alcohol solution, preferably octanol, which contains silver particles. Each silver particle is coated with a layer of oleic acid. An electrode, preferably made of silver, is also disposed in the anhydrous solution. A direct current voltage is then established on the electrode, which causes the silver particles to plate onto the superconductor. After electrophoresis, the now-plated superconductor is heated to nine hundred degrees centigrade (900.degree. C.) for approximately one (1) minute.
