论文摘要
在本报告中，研究了冷烧结过程（CSP）对10 mol％GD掺杂陶瓷（GDC）的电化学特性的影响。高纯度纳米级GDC粉末通过冷水中的冷烧结过程（CSP）烧结，然后在1000°C下进行通量。所得的CSP陶瓷表现出高度密度（〜92％），超细晶粒尺寸约为100 nm。该样本说明了在中等/高温和室温下的机电特性与通过常规射击制备的样品，即在1450°C下在空气中烧结的样品。此外，在CSP样品中还观察到了较大的蠕变常数以及低弹性模量和硬度。
In this report, the effect of the cold sintering process (CSP) on the electro-chemo-mechanical properties of 10 mol% Gd-doped ceria (GDC) is investigated. High purity nanoscale GDC powder is sintered via a cold sintering process (CSP) in pure water followed by post-annealing at 1000 °C. The resultant CSP ceramics exhibits high relative density (~92%) with an ultrafine grain size of ~100 nm. This sample illustrates comparable electrochemical properties at intermediate/high temperatures and electromechanical properties at room temperature to the sample prepared via conventional firing, i.e. sintering in the air at 1450 °C. Moreover, a large creep constant as well as a low elastic modulus and hardness are also observed in the CSP sample.
