Comparable experiments on the analysis of oxygen impurities in uranium carbides by vacuum-fusion and inertgas-fusion methods havebeen performed, using various temperatures and bath compositions (iron, cobalt, and nickel). The latter fusion method proved tobe unsatisfactory.Best results were obtained by the vacuum-fusion method, using a cobalt bath at 1900-2000°C. Thermodynamic evaluations were in good agreement with the experimental results. Metallographie and autoradiographic investigations explained that the unfavourable behaviour of powdered samples compared to massive samples was above all dueto the increasing graphite precipitation in the bath. |
