|Abstract:||The thermal interaction of yttrium aluminosilicate glass with cerium, plutonium and uranium oxides at temperatures up to 1200°C has been studied by means of differential scanning calorimetry (DSC), X-ray diffraction (XRD), and secondary electron microscopy (SEM). The glass, a candidate for joining and sealing advanced fuel cladding materials, such as SiC, undergoes a recrystallisation process above 1000°C providing a mixture that exhibits two melting points at 1379 and 1410°C. Samples containing glass and actinide oxide mixtures did not form new phases, nor did the actinide oxides influence the recrystallisation behavior of the glass.|
