摘要：

The thermal interaction of yttrium aluminosilicate glass with cerium, plutonium and uranium oxides at temperatures up to 1200 degrees 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 silicon carbide (SiC), undergoes a recrystallization process above 1000 degrees C providing a mixture that exhibits two melting points at 1379 and 1410 degrees C. Samples containing glass and actinide oxide mixtures did not form new phases, nor did the actinide oxides influence the recrystallization behavior of the glass. (C) 2011 Elsevier B.V.
