Abstract
A method for heat processing a superconductor wire which has a protective silver cladding includes the steps of attaching the coated wire to a spool and then rotating the spool to wind the wire around the spool in juxtaposed coils. As the wire is being wound around the spool, the portions of the wire which are not yet coiled are drawn through a container which holds a paint that contains a silver diffusion inhibiting material. The diffusion inhibiting material is consequently deposited onto the silver cladding of the superconductor wire, and the coiled wire is subsequently placed in a furnace. The wire is heat processed in the furnace as appropriate for the particular type of superconductor material. The diffusion inhibitor material prevents diffusion of silver during the heat processing between portions of the wire which contact each other.
