Oxygen potentials of PuO_(2-x)

摘要

Oxygen potentials of PuCO_(2-x) were measured at temperatures of 1473 - 1873.K by thermo-gravimetry. The oxygen potentials were determined by in situ analysis as functions of oxygen-to-metal ratio and temperature. The measurement data were analyzed on the basis of defect chemistry and an approximate equation was derived to represent the relationship among temperature, oxygen partial pressure, and deviation x in PUO_(2-x).
