Abstract
A method of electroless deposition of gold from a solution onto ceramic oxide superconducting particles is characterized by the steps: (1) adding gold chloride to organic solvent-optional reducing agent for the gold chloride to provide a gold solution, (2) mixing the ceramic oxide superconducting particles with the gold solution, to provide a suspension, (3) optionally adding reducing agent for the gold chloride, (4) stirring and heating the suspension to deposit a layer of gold metal on the particles, and (5) separating the particles.
