Abstract : A silver coated superconducting ceramic powder made 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 superconducting ceramic particles which are uniformly coated with a thin layer of silver metal. The powder can be cold worked (e.g., swaged, forged etc.) to form superconducting structures such as rods or wires.
