Abstract

In this thesis, the rapid solidification of the YBa2 Cu3 O7 - x compound using the shock tube method was studied as route to continuous production of the 123 superconductor. The as quenched shock tube flakes were characterized using XRD, Debye Scherrer, SEM and the DSC. Phase separation was observed in the as quenched flake. The as quenched flakes were largely glassy and had a Tg (584°C-596°C) below the T cryst. (665°C-780°C ) making it a formable glass (percentage penetration 50% to 55%). Annealing the as quenched products in flowing oxygen for 8 hours at 850°C did not produce the YBa2Cu30r-x Orthorhombic superconducting phase.
