Processing of Mixed Oxide Superconductors
Abstract
High Tc superconductivity has continued to change at a rapid pace. Since the last report, two new compounds have been reported with even higher critical temperatures and possibly higher critical currents. Less encouraging is a recent experiment reported from IBM from which it appears that even clean low angle grain boundaries can limit the current densities. If confirmed this means that in future all practical conductors will have to consist of carefully aligned grains, probably melted in some way to fuse the boundaries together. Fortunately, all the techniques developed in this project are applicable to a side range of materials, but we have decided to postpone any more HIPing until we have prepared better orientated samples. Most of the work is described in the three enclosed papers and only the main conclusions will be summarised in this report. The topics are classified under four headings.
