Abstract:
Supercritical carbon dioxide was explored as a medium for nucleation and growth processes for ceramic oxide superconductors. The high temperature superconductor examined, YBa₂Cu₃O₇₋ₓ (YBC), was found to be stable upon limited exposure to CO₂. The solubility of the compound was studied in the region near the critical point using spectrophotometry. The species solubilized was indirectly identified by elemental analysis. Preliminary studies on the potential of the medium for metastable synthesis, comminution, and crystallization were conducted and showed promise for further development.
