چکیده انگلیسی
A series of Zr1-xNd xO2-x/2 (0 â¤Â x â¤Â 1) ceramics was prepared by solid-state reaction method. The effects of Nd content on the phase evolution were investigated. The chemical durability of resulting waste forms was also examined. The results show that the ceramics with x < 0.1 show monoclinic and cubic zirconia phase, with 0.2 â¤Â x < 0.4 exhibit a single cubic phase, with 0.4 â¤Â x â¤Â 0.6 exhibit a single pyrochlore phase, with 0.6 < x < 0.8 exhibit a single cubic phase and remain cubic phases and hexagonal Nd2O3 when 0.8 â¤Â x â¤Â 1. The unit cell parameters of the Nd-doped zirconia samples increase as the Nd content increases. Moreover, the normalized element release rates of Nd element in Nd-doped zirconia ceramics firstly decrease with leaching time and almost no change after 21 days (â¼0â6 g mâ2 dâ1), demonstrating its good chemical durability.
