This study evaluated the effect of reaction conditions on the extent and uniformity of 17O-labeled YBa2Cu3O7-x. It was shown by 17O NMR spectroscopy and high-resolution SIMS that statistical 17O-enrichment is achieved at high temperatures by synthesis from oxides under an 17O2 atmosphere, or by direct 17O2 exchange of preformed YBa2Cu3O7-x. Nonuniform enrichment can be achieved at low temperatures and with the use of short reaction times. An 17O2 circulator is described which proved useful for handling, purifying, and recovering the labeled oxygen.
