文摘
- •
Synthesis of Nd2xZr1−xO2+x ceramics by a coprecipitation route.
- •
Dissolution kinetics studied at 90 °C in C(HCl) = 0.1 M in batch and dynamic setups.
- •
Data show a higher stability of Zr-based B-sublattice in the pyrochlore structure.
- •
Batch and dynamic steady state dissolution rate of pyrochlore in good agreement.
- •
No significant difference in dissolution rates of defect fluorite and pyrochlore.
