Hydrolytic Stability of Y2.5Nd0.5Al5O12-Based Garnet Ceramics under Hydrothermal Conditions

  • Published:
Inorganic Materials Aims and scope

Abstract—

We have studied the hydrolytic stability of Y2.5Nd0.5Al5O12-based garnet ceramics produced by spark plasma sintering. The ceramics have been tested under hydrothermal conditions in an autoclave and, for comparison, in static mode at room temperature. The mechanisms of yttrium and neodymium leaching from the ceramics have been identified.
