Abstract—

We have studied the hydrolytic stability of Y_2.5Nd_0.5Al₅O₁₂-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.

Y2.5Nd0.5Al5O12基石榴石陶瓷在水热条件下的水解稳定性

摘要——

我们研究了放电等离子烧结制备的Y _2.5 Nd _0.5 Al ₅ O ₁₂基石榴石陶瓷的水解稳定性。陶瓷已经在高压釜中的水热条件下进行了测试，为了比较，在室温下以静态模式进行了测试。已经确定了从陶瓷中浸出钇和钕的机制。
