Abstract: A series of zirconolite-based borosilicate glass-ceramics were synthesized by in-situ heat treatment. The effects of MoO3 content on crystalline phase, microstructure and chemical durability of the zirconolite-based borosilicate glass-ceramics were investigated. The results show that glass transition temperature increases slightly with increasing content of MoO3. In the absence of the yellow phase, the main crystalline phase is zirconolite for all of the samples. When the content of MoO3 up to 4.88wt%, spherical powellite crystals appear in the bulk of glass-ceramics. However, the glass-ceramic containing 7.14wt% of MoO3 produced yellow phase. The SEM results show that the increase of MoO3 content has effects on the grain size and the number, but has no significant effect on the morphology and distribution of zirconolite crystals. In the case of no yellow phase, all the glass-ceramic samples are evenly distributed with excellent chemical stability. For the CM0, CM2 and CM4 samples, the normalized leaching rates of Si, Ca and Mo of these samples stabilize at 14 days and is of the order of 10-3 g·m-2·d-1and the leaching rates of Ce stabilize after a sharp drop on the third day, and fell as low as 10-6 g·m-2·d-1.
