Abstract : This patent discloses a process for silver coating superconducting ceramic powder by: (1) coating the superconducting ceramic powder particles with AgNO3; (2) melting the AgNO3 so that it wets and forms a uniform coating over the surfaces of the particles; and (3) decomposing the AgNO3 to form a thin, uniform coating of silver metal on the surfaces of the particles. The product is a loose powder of the superconducting ceramic particles which are uniformly coated with silver metal metal. The powder can be cold worked (e.g., swaged, forged, etc.) to form superconducting structures such as rods or wires.
