The objective of this study was to produce bulk high Tc superconductor YBa2Cu3O7-x with microwave conductivity at least as good or better than that of copper. The subsequent aim was to fabricate a cylindrical wave guide using this material. The ultimate goal of this study is to produce YBa2Cu3O7-x with microwave conductivity exceedingly higher (at least two orders of magnitude better) than that of copper. In principle, this is possible if the microstructure of the superconductor material is carefully controlled. The above-stated goal could be easily achieved if the large single crystals of YBa2Cu3O7-x are available or if the inside surface of a suitable substrate material in the form of hollow cylinder, could be coated with the superconductor material of high quality. The former approach, currently, seems to be far from practical realization.
