In this research, Zr-doped Gd2Ti2O7 pyrochlores, with the composition of Gd2(Ti1-xZr x )2O7, were firstly synthesized by self-propagating high-temperature synthesis plus quick pressing (SHS/QP) using CuO as oxidant and Ti reductant. To improve radiation resistance titanate–pyrochlore, up to 35 at% Zr was incorporated substitute site pyrochlore (Gd2(Ti0.75Zr0.35)2O7). XRD SEM microstructural characterizations showed formation a composite ceramic major phase minor Cu phase. The generated...
Synroc is recognized as the second-generation waste matrice for nuclear disposal. Zirconolite one of most durable minerals. In this study, Gd and Hf were selected surrogates trivalent tetravalent actinide nuclides. Gd-bearing Hf-zirconolite (Ca1-xHf1-xGd2xTi₂O₇) ceramic forms rapidly synthesized from a self-propagating technique using CuO oxidant. The results indicate that can concurrently replace Ca sites. However, Gd₂O₃ could not completely be incorporated into lattice structure...
Abstract In this study, the synthesis of single‐phase zirconolite powder was explored using two‐step route combustion ( CS ) plus acid treatment. Zirconolite/Cu composite firstly produced from reaction CuO and Ti as oxidant reductant. After pickling desiccation, refined zirconolite‐rich ceramic obtained with bimodal particle size distribution. The finally preformed calcined at 1050‐1300°C for 6‐48 hours, which resulted in bulk density Vickers hardness 4.02 g/cm 3 11.54 GP a after sintering...
Zirconolite is recognized as one of the most durable waste matrices for disposal high-level radioactive wastes (HLWs). In this study, HfO2 was employed surrogate tetravalent actinides. Hf-bearing zirconolite-based composite forms (CaZr1−xHfxTi2O7) were rapidly prepared by combustion synthesis (CS) using CuO oxidant, where quick pressing (QP) introduced to obtain densified samples. Similar solid state reaction process, Zr site zirconolite can be totally occupied Hf (x = 1.0) under CS...
In this study, zirconolite (CaZrTi 2 O 7 )/Mo composite was rapidly synthesized by self‐propagating high‐temperature plus quick pressing ( SHS / QP ) technique using MoO 3 as the oxidant. As surrogate of tetravalent actinide nuclides, up to 50 at.% CeO (about 17.5 wt% raw material) introduced substitute Zr site zirconolite. Perovskite (CaTiO and rutile TiO were inevitably produced after incorporation . The partially reduced trivalent state, which promotes substitution Ce into Ca sites...
In this study, the zirconolite-rich composite was rapidly synthesised from self-propagating high-temperature synthesis plus quick pressing using MoO3 as oxidant and Ti reductant. As a surrogate of trivalent actinides, Nd introduced to substitute Ca site zirconolite Al employed charge compensator replace (nominally Ca1−xNdxZrTi2−xAlxO7). The phase composition occupancy were analysed after Nd2O3 addition. Nd-bearing produced major ceramic phase. mostly substitutes sites zirconolite, which...
The present study was conducted to the catalytic performance of sewage sludge char on NH3 decomposition by using a fixed bed reactor. results indicated that exhibited strong activity towards decomposition, which highly influenced temperature and atmosphere. influence atmosphere investigated at 973 K, it showed greatly promoted with presence O2, major product oxidation catalyzed relatively fresh N2 rather than NO. In contrast, suppressed H2O introducing, there significant amount NO being...
